I'm having trouble getting tmux to display lines for borders. They are being created with x and q. It's a debian squeeze server and the locale is set to en_US UTF8. I also tried adding
# instructs tmux to expect UTF-8 sequences
setw -g utf8 on
set -g status-utf8 on
lines to .tmux.conf. Nothing seems to work. I'm not sure if it's a locale issue or not. It displays correctly on other servers, but not the debian. I appreciate any tips you could offer! Thanks...
I had the same problem with PuTTY and Windows 8 when connecting to tmux running on a Debian Squeeze machine. Even when setting the charset to UTF-8 in PuTTY (in the settings under Window > Translation > Remote character set) I didn't get the correct line drawing.
Setting the Remote character set to "Use font encoding" did the trick for me.
There is some mismatch between your terminal emulator and the terminfo database entry being used by tmux (the one named by the TERM environment variable when you start/attach to a tmux server).
Per the VT100 User Guide, Table 3-9: Special Graphics Characters, when the “special graphics set” is selected, x is used to draw the “Vertical bar” and q is used to draw “Horizontal line - Scan 5”.
Under terminfo, the VT100 special graphics characters are available as a part of the Alternate Character Set functionality; see the “Line Graphics” section of the terminfo(5) man page.
Probably (on your Debian server) the effective terminfo database entry indicates that ACS is available, but your terminal emulator is not actually responding to the specified control sequences.
The tmux CHANGES file indicates that some terminal emulators (e.g. Putty) do not respect the ACS control sequences when they are in UTF-8 mode. Thus, tmux 1.4 has a change that makes it always use UTF-8 characters instead of ACS sequences when the attaching client specifies that it can handle UTF-8 (i.e. when attaching, -u was given or UTF-8 is present in LC_ALL, LC_CTYPE or LANG; the utf8 window option is about what tmux should expect from the programs it runs, not what it can send to the attached client).
Debian “squeeze” only includes tmux 1.3, so your tmux probably does not have the “prefer UTF-8 line drawing” feature (unless it pulls from a backports source).
If you can not fix your terminal emulator nor upgrade to at least tmux 1.4, then you might be able to use tmux’s terminal-overrides option to unset the ACS-related capabilities so that tmux will fall back to ASCII line drawing. In your .tmux.conf (on the Debian system):
set-option -ga terminal-overrides ',*:enacs#:smacs#:rmacs#:acsc#'
Try setting the character set to "UTF-8" and "Use Unicode line drawing code points" under Window -> Translation in your putty settings.
I had the same problem with Putty when launching tmux on Linux 12.04 machine. Even setting the charset to UTF-8 in PuTTY (in the settings under Window > Translation > Remote character set) didn't solve the problem.
Launching tmux with -u option did the trick (tmux -u)
If you have Putty 0.73 or higher open settings, expand Window category, then select Translation. Check 'Enable VT100 line drawing even in UTF-8 mode':
I ran thru the gamut of suggestions including:
confirming locale and UTF-8 setting in PuTTY
exporting NCURSES_NO_UT8_ACS=1
manually trying various fonts and PuTTY translation selections
Above did not work. Dialog displays showed qqqq... and xxxx with various corner characters.
Changing all dialog calls to include --ascii-lines was an option but it would involve a lot of script changes.
Best recommendation was to change the Remote Character Set to Use font encoding.
PuTTY Change Settings --> Window --> Translation --> Remote Character Set --> Use font encoding
Left all other PuTTY settings default.
I changed the setting in Putty for terminal to Latin-1 and that seemed to fix the problem.
If you are using KiTTY there is a check box under Windows -> Translation tab, that is called "Allow ACS line drawing in UTF". It needs to be checked:
For me the issue was I forgot to make a locale.conf file when I setup this Arch Linux box. Below line fixed the issue, substitute your own language. A reboot was not required for me.
echo "LANG=en_US.UTF-8" > /etc/locale.conf
under windows/ putty the font you use has to have the characters for it to display
set translation "UTF-8" and "Use Unicode line drawing code points" and font to "courier-new" and most of those problems go away
It seems the font choice is a confusing factor here, to wit:
Lucida sans doesn't display UTF-8 line drawing, only - + | (pipe)
substitution
Courier New Bold does horizontal lines but |
substitution for vertical
Courier New Normal does 'em all.

iTerm2 Version is Build 2.1.1
Vim Version is
VIM - Vi IMproved 8.0 (2016 Sep 12, compiled Nov 29 2017 18:37:46)
Included patches: 1-503, 505-680, 682-1283
Compiled by root#apple.com
And I Installed the Vundle plugin
And when I open vim in iTerm2 with oh-my-zsh, the $p appears at the first line.
It doesn't appear with Terminal.app of Apple?
How to solve this problem?
vim is assuming that iTerm2 is xterm (not a good assumption), and attempting to determine the state of the cursorBlink resource by sending an escape sequence containing $p which iTerm2 does not handle properly (see source-code for vim for the escape sequence, and also where it uses the feature). While vim starts with the TERM setting (i.e., "xterm"), it does make a few checks to exclude things like gnome-terminal as noted in the source code comment. But iTerm2 happens to fool vim in this case. So the result goes to the screen.
In XTerm Control Sequences that is documented like this:
CSI ? Ps$ p
Request DEC private mode (DECRQM). For VT300 and up, reply is
CSI ? Ps; Pm$ y
where Ps is the mode number as in DECSET/DECSET, Pm is the
mode value as in the ANSI DECRQM.
Two private modes are read-only (i.e., 1 3 and 1 4 ), pro-
vided only for reporting their values using this control
sequence. They correspond to the resources cursorBlink and
cursorBlinkXOR.
Although vim is fooled here, the problem is due to iTerm2, for which you've probably set the TERM environment variable to xterm-256color, or something like that. It doesn't match iTerm2's behavior very well (the function keys don't match up, etc). ncurses provides a better one. But out-of-the-box MacOS has a terminal database that's about ten years old, and lacks that entry. To get a good terminal database (i.e., one where you could set TERM to iterm2), you could do that with MacPorts or home-brew.
Running infocmp to get a measure of the differences between the (correct) iterm2 entry and linux, xterm-256color shows that
it's actually closer to nsterm-256color (a correct entry for Terminal.app which Apple doesn't provide) with 38 lines of difference,
next closest linux with 76 lines and
still further away from xterm-256color with 94 lines.
The feature that's missing or mis-implemented in iTerm2 isn't in the terminal description: it's a special feature that vim has to guess about.
As mentioned above, this $p is due to vim sending a control sequence for a cursor blink request. In your .vimrc, you can turn off the cursor blink request by clearing the t_RC terminal option. I wrapped this in a conditional which turns it off only for 256 color terminals.
if &term =~ '256color'
set t_RC=
endif
Setting the terminal explicitly to linux solved it for me:
export TERM=linux
The p means print, which is the command the range is being given to, and yes.. it displays to you what is in that range.
In vim you can look at :help :range and :help :print to find out more about how this works. These types of ranges are also used by sed and other editors.
They probably used the 1,$ terminology in the tutorial to be explicit, but note that you can also use % as its equivalent. Thus, %p will also print all the lines in the file.
I have a problem with my Xterm and I can't figure out what is wrong:
I need to enable the option *selectToClipboard in my Xterm to be able to copy text in the terminal.
To do so i firstly tried to "manually" start xterm with the option with the following command: xterm -xrm 'xterm*selectToClipboard: true' which work very well.
Then to enable the option each time xterm is started I put the following line xterm*selectToClipboard: true in my ~/.Xresources and I used the command xrdb -merge ~/.Xresources to update the settings but it doesn't work: Xterm starts but the option isn't enabled and I can't copy text from the terminal whereas all the other options in the Xresources are enabled and work fine.
Does anyone have an idea of what could cause this problem?
X resources are case-sensitive. The xterm manual documents this as
selectToClipboard (class SelectToClipboard)
Tells xterm whether to use the PRIMARY or CLIPBOARD for SELECT
tokens in the selection mechanism. The set-select action can
change this at runtime, allowing the user to work with programs
that handle only one of these mechanisms. The default is
"false", which tells it to use PRIMARY.
The feature was added to xterm in patch #209 (2006). It is not an optional feature. So (assuming you have typed the command-line as given), there are a few possibilities to check:
you could be running an older version of xterm. To check this, run
xterm -v
The -v version option of xterm will have it print a one-line message showing the patch-level along with the configuration for which it was compiled, e.g.,
XTerm(261)
The feature can be set/reset using an escape sequence, as noted in XTerm Control Sequences:
CSI ? Pm h
DEC Private Mode Set (DECSET).
...
Ps = 1 0 4 1 -> Use the CLIPBOARD selection. (This enables
the selectToClipboard resource).
Your shell initialization may have something which sends this sequence.
The xrdb -query is one way to check for resource-settings, but it is not infallible. A better tool would be appres, e.g.,
appres XTerm
appres UXTerm
depending on whether xterm is run with/without the UXTerm application defaults. In contrast to xrdb, appres shows resource settings after taking into account the "app-defaults" files. (It does not see resources applied only to an instance of xterm such as the -xrm option).
tmux has a feature which can interfere with selections (whether to primary or clipboard). That is called set-clipboard, and is commented upon here:
Enabling mouse in tmux conflicts with paste in X [duplicate]
Re: iTerm2 support for set-clipboard
Short answer:
just need to add the line bellow in your /etc/X11/app-defaults/XTerm file
*selectToClipboard: true
Long answer:
If you look at man pages xterm(1):
man xterm
FILES
The actual pathnames given may differ on your system.
...
/etc/X11/app-defaults/XTerm
the xterm default application resources.
/etc/X11/app-defaults/XTerm-color
the xterm color application resources. If your display supports color, use this
*customization: -color
in your .Xdefaults file to automatically use this resource file rather than /etc/X11/app-defaults/XTerm. If you do not do this, xterm uses its compiled-in default resource settings for colors.
...
I did not find any reference to a user configuration file to set XTerm application defaults, except for XTerm-color, so I don't think it exists.
I'm trying to get 256 colors in the fantastic ConEmu-Maximus5 console.
Update: Now it only shows 8 colors. I know because '$tput colors' output is '8'
I have followed the instructions and activated:
TrueMod (24-bit color) support
Inject ConEmuHk
ANSI x3.64 / xterm 256 colors
I don't understand what to do with 'check off whether the buffer / slide.'
I'm in windows 7.
I start ConEmu with a custom direct link, so it loads cygwin bash file.
"C:\Program Files\ConEmu\ConEmu64.exe" /cmd ""C:\cygwin\bin\bash.exe" --login -i"
In my bashrc profile I have -> export TERM=cygwin
This is my custom command prompt:
function prompt {
local RED="\[\033[0;31m\]"
local GREEN="\[\033[0;32m\]"
local COOLRED="\e[38;5;173m"
local COOLGREEN="\e[38;5;113m"
PS1="$COOLRED\u#\h $LIGHT_COOLGREEN\$PWD \[\e[0m\] > "
}
prompt
The value of ConEmuANSI in ON, by the way.
I have some screen shots:
As you can see the command prompt looks very extravagant because it doesn't like the 256 color settings. If i substitute the variables COOLRED and COOLGREEN with RED and GREEN, then it looks ok, but it's not 256 colors.
More screenshots of the settings:
And the last sceen shot it's cygwin's mintty. Everything is ok there. Full 256 color supported. It's a shame mintty doesn't have tabs. That's mostly the reason why I'm trying to move to ConEmu.
Thank you very much for helping!!!
Bash does not send ANSI sequences to console. It tries to process them itself. And, because *nix terminal is generally only 8-color (not taking into account 256-color mode), bash uses 8-color palette instead of 16-color palette which is common to Windows terminal.
I think, 256-colors works in mintty because _isatty returns zero in that terminal. But it returns non zero value under ConEmu. May be in future builds I solve this puzzle (how to create real terminal with PTY features for some applications).
As for the question
You have no need in 256-colors In fact. To redefine prompt palette you may use "Extend foreground colors with background" feature. In breaf - set up colors 16, 17, etc. in ConEmu, set prompt background in bash to #5 (configurable in ConEmu), and voila.
There was a small bug in ConEmu "Extend..." processing. Use build 121016 or later.
PS1="\e[30;45m\u#\h \e[34;45m$PWD \[\e[0m\] > "
Following info does not match the question, but may be useful
Current version does not support 256-color mode in 'whole' console buffer (limitation, yes, removing it in plans).
So, you can go 2 ways
totally disable scrollback buffer (many ways, for example "cmd -cur_console:h0")
work in the bottom of the scroll-buffer.
I also couldn't get 256 color support to work (the colors would show up, but they looked the same as the 16-color palette). I switched to the "xterm" color scheme and now it works in native Windows executables (such as Python) but not in anything that uses Cygwin. Cygwin appears to have terminal-escape-sequence processing that you can't turn off, which defeats the ConEmuHk injection.
This is documented on the ConEmu wiki, here.
I had this weird problem and the weird solution and somehow it works. and don't know if this is with others too, just some info-sharing in case this shall be helpful.
I like colouring my consoles and like to utilize the full real 256 bits of RGB colouring.
After confuguring as in the conemu/CMDer (i used the forked one) instruction. my 256bit coloring test looked like this.. After mucking around a bit and testing with my bash 256bit capability. i.e running this command:
for i in {1..16384}; do echo -en "\e[38;5;${i}mTest";done
*note supposed to be {1..256}, but i had to force it for a longer colour prints, so just took a longer random number..
giving the result:
But running some 2-3 times, i saw this clean gray shade suddenly
and it worked then on..
weird but i got this working. Could it be that CMDer is somehow not using the full 256 bit because of optimizing reason and it get triggered when it is kicked in??,
PS: my CMDer cmd for the console:
-cur_console:fp -cur_console:d:"C:\WS":P:"<Cobalt>":t:"test":C:"C:\Arbeit\tools\Iconka-Buddy-Ninja.ico" set "PATH=%ConEmuDrive%\Program Files\Git\usr\bin;%PATH%" & "%ConEmuDrive%\Program Files\Git\git-bash.exe" --no-cd --command=%ConEmuBaseDirShort%\conemu-msys2-64.exe /usr/bin/bash.exe -l -i
local COOLRED="\e[38;5;173m"
local COOLGREEN="\e[38;5;113m"
Those \es are probably from an e.g. C printf string. You don't want them in a shell script. Stick with the original \033 notation. Also you are missing the closing \]. These lines should now read
local COOLRED="\[\033[38;5;173m\]"
local COOLGREEN="\[\033[38;5;113m\]"
I'm using OSX snow leopard, for the record.
When I use emacs straight from terminal, I have a color set (e.g. for c/c++) that I'm very happy with---green on black, red comments, colored key words... etc etc. Some of this is set in my 'terminal preferences', and some is in my ~/.emacs file (see below). When I run emacs from screen, the basic color-scheme is the same (green on black), but the coloring is different (e.g. comment characters are red, but not the entire comments) -- and really annoying.
Any help would be appreciated!
In my '.emacs' file (this stops working in gnu-screen emacs):
(global-font-lock-mode t)
(custom-set-faces
'(font-lock-comment-face
((((class color) (background light))
:foreground "tomato")
)))
In my '.screenrc' file:
shell -$SHELL # colors still don't work without this
#term xterm-256color # using this doesn't fix the colors (suggested on some forums)
altscreen on
startup_message off
I thought that the command 'shell -$SHELL' in my .screenrc file made the command prompt in screen the same as the default --- it does make my command line say 'computername:/DIR/ username$' instead of just 'bash-3.2$'
=================================================================
Solution: Thanks to Greg E.
I needed to set my terminal emulator in screen to match that of my normal shell. To do this, I added
export TERM='xterm-color'
to ~/.bash_profile
For some reason, 'term xterm-color' in the '~/.screenrc' file didn't work.
My suspicion is that, while your terminal may be compiled with support for more than the standard 16 colors, your particular version of GNU screen may not be. I'm not very familiar with OSX, but on Linux I'd check whether the output of tput colors differs between a plain terminal and one running screen (I'd expect there to be some OSX equivalent if tput is not available). If it does, you may need to install (or manually compile) a different build of screen that includes support for additional colors (normally, 256 is the maximum, but 88 is also common, while 16 is the default minimum).
Edit: Ultimately, the correct solution proved to be manually setting the $TERM environment variable (see comments below).
Okay, so I finally got myself a MacBook Air after 15 years of linux. And before I got it my big concern was UTF-8 support because no matter if I get files sent to me from windows or mac-clients theres always issues with encoding, while on ubuntu I can be sure that all output no matter what program will produce perfect utf-8 encoded data.
And now on my second day (today) with OS X Im tearing my hair of by frustration. Why?
When I open Nano and type some swedish characters like ÅÄÖ in it, it puts out blank characters at the end of the line (which i guess is the other byte in each character)
When I open python and try using swedish characters, it does not output anything at all
When I connect to a Ubuntu server trough SSH I cant type åäö in bash, tough it works in VIM (still trough SSH). And in nano backspace does not work, but if check the box "Delete sends ctrl+H" in the Terminal preferences, backspace starts working in nano but stops working in VIM.
I've tried unchecking all other encodings then UTF-8 in terminal preferences but that does not seem to work either.
I'm sure that every non US-person must have the same issues, so hove do I fix them? I just want full UTF-8 support... :'(
For me, this helped:
I checked locale on my local shell in terminal
$ locale
LANG="cs_CZ.UTF-8"
LC_COLLATE="cs_CZ.UTF-8"
Then connected to any remote host I am using via ssh and edited file /etc/profile as root - at the end I added line:
export LANG=cs_CZ.UTF-8
After next connection it works fine in bash, ls and nano.
Go to Terminal -> Preferences -> Advanced (Tab) go down to International and select Unicode (UTF-8) as Character Encoding.
And tick Set locale environment variables on startup.
Unfortunately, the Preferences dialog is not always very helpful, but by tweaking around you should be able to get everything working.
To be able to type Swedish characters in Terminal, add the following lines to your ~/.inputrc (most likely you must create this file):
set input-meta on
set output-meta on
set convert-meta off
This should do the work both with utf8 and other codings in bash, nano and many other programs. Some programs, like tmux, also depends on the locale. Then, adding for instance export LC_ALL=en_US.UTF-8 to your ~/.profile file should help, but keep in mind that a few (mainly obscure) programs require a standard locale, so if you have trouble running or compiling a program, try going back to LC_ALL=C.
Some references that may be helpful:

http://hints.macworld.com/article.php?story=20060825071728278
The following is a summary of what you need to do under OS X Mavericks (10.9). This is all summarized in
http://hints.macworld.com/article.php?story=20060825071728278
Go to Terminal->Preferences->Settings->Advanced.
Under International, make sure the character encoding is set to Unicode (UTF-8).
Also, and this is key: under Emulation, make sure that Escape non-ASCII input with Control-V is unchecked (i.e. is not set).
These two settings fix things for Terminal.
Make sure your locale is set to something that ends in .UTF-8. Type locale and look at the LC_CTYPE line. If it doesn't say something like en_US.UTF-8 (the stuff before the dot might change if you are using a non-US-English locale), then in your Bash .profile or .bashrc in your home directory, add a line like this:
export LC_CTYPE=en_US.UTF-8
This will fix things for command-line programs in general.
Add the following lines to .inputrc in your home directory (create it if necessary):
set meta-flag on
set input-meta on
set output-meta on
set convert-meta off
This makes Bash be eight-bit clean, so it will pass UTF-8 characters in and out without messing with them.
Keep in mind you will have to restart Bash (e.g. close and reopen the Terminal window) to get it to pay attention to all the settings you make in 2 and 3 above.
Short versatile answer (fits to other national languages, even Lithuanian or Russian)
open Terminal
edit .profile in home directory - nano .profile or in Catalina or newer nano .zshenv
add line export LC_ALL=en_US.UTF-8
press Ctrl+x and Y (exit and save)
This solved for me even small country rare national characters. You may need to close and open Terminal to make changes effective.
Also if you like Linux behavior (use lot of Alt shortcuts like Alt+. or Alt+, in mc) then you should disable Mac style Option key function:
Terminal->Preferences->Profiles->Keyboard and check box:
Use Option as Meta key
To make nano work as you want it to, try:
export LANG="UTF-8"
Or get a newer version of nano via MacPorts:
# cf. http://www.macports.org/install.php
port info nano
port variants nano
sudo port install nano +utf8 +color +no_wrap
With respect to ssh & UTF-8 issues comment out SendEnv LANG LC_* in /etc/ssh_config.
See: Terminal in OS X Lion: can't write åäö on remote machine
My terminal was just acting silly, not printing out åäö. I found (and set) this setting:
Under Terminal -> Preferences... -> Profiles -> Advanced.
Seems to have fixed my problem.
Check whether nano was actually built with UTF-8 support, using nano --version. Here it is on Cygwin:
nano --version
GNU nano version 2.2.5 (compiled 21:04:20, Nov 3 2010)
(C) 1999, 2000, 2001, 2002, 2003, 2004, 2005, 2006, 2007,
2008, 2009 Free Software Foundation, Inc.
Email: nano#nano-editor.org Web: http://www.nano-editor.org/
Compiled options: --enable-color --enable-extra --enable-multibuffer
--enable-nanorc --enable-utf8
Note the last bit.
Since nano is a terminal application. I guess it's more a terminal problem than a nano problem.
I met similar problems at OS X (I cannot input and view the Chinese characters at terminal).
I tried tweaking the system setting through OS X UI whose real effect is change the environment variable LANG.
So finally I just add some stuff into the ~/.bashrc to fix the problem.
# I'm Chinese and I prefer English manual
export LC_COLLATE="zh_CN.UTF-8"
export LC_CTYPE="zh_CN.UTF-8"
export LC_MESSAGES="en_US.UTF-8"
export LC_MONETARY="zh_CN.UTF-8"
export LC_NUMERIC="zh_CN.UTF-8"
export LC_TIME="zh_CN.UTF-8"
BTW, don't set LC_ALL which will override all the other LC_* settings.
Try
Having a Powerline compatible font installed https://github.com/powerline/fonts
Setting these ENV vars in .zshrc or .bashrc:
LANG="en_US.UTF-8"
LC_COLLATE="en_US.UTF-8"
LC_CTYPE="en_US.UTF-8"
LC_MESSAGES="en_US.UTF-8"
LC_MONETARY="en_US.UTF-8"
LC_NUMERIC="en_US.UTF-8"
LC_TIME="en_US.UTF-8"
LC_ALL="en_US.UTF-8"
Just add a file on remote server
$ sudo nano /etc/environment
LANG=en_US.utf-8
LC_ALL=en_US.utf-8
PS: Top answer has a suggestion to change /etc/profile file on remote server, it works, but this file is often overwritten by system, and doesn't help for long.
/etc/profile file contains disclaimer:
It's NOT a good idea to change this file unless you know what you are doing. It's much better to create a custom.sh shell script in /etc/profile.d/ to make custom changes to your environment, as this will prevent the need for merging in future updates.
In my case, simply using the uxterm command instead of xterm solved the problem. It's available in /opt/X11/bin/uxterm by installing the XQuartz package provided by Apple.
