Getting a strange character appearing at the end of each custom option in a PDF invoice. See the image below. Any ideas what this character might be?
It might be the case that the current PDF's font library that is used, doesn't support certain characters.
By default it uses the following Font library for PDF Generation: LinLibertineC_Re-2.8.0.ttf
In order to change the default PDF Font:
Get the desired font library's TTF-file and place it in the lib folder of your Magento installation.
Edit the following files (better mirror it instead of editing core files directly) in order to switch the font:
/app/code/core/Mage/Sales/Model/Order/Pdf/Invoice.php
/app/code/core/Mage/Sales/Model/Order/Pdf/Items/Abstract.php

I have a PowerPoint template. When this template was passed off It included some special fonts that I needed to remove because it was throwing warnings when users opened them up.
When I use the "replace fonts" feature it does not remove the font. I deal a lot with the XML properties of these templates because some of the content is generated dynamically when a report is run. I can still see in the slides the font is present
<a:buFont typeface="Poppins"/> the other is <a:buFont typeface="Noto Sans Symbols"/>
Which both appear to be bullet list fonts? There are no lists in the view though...
Removing it from the XML itself is not an option because when I update the template again it will override that and given that doesn't happen often I will have forgotten all about this. I need to fix this in the template so I can then export it out.
I have edited all the text I can see to either Ariel or Calibri but this Poppins font is still in there and I have no idea how to get it out.
Specifics are
Powerpoint version is 16.36
The program is actually Powerpoint for Mac (if that matters)
If anyone solved a similar issue and can give me some direction it would be much appreciated.
The buFont tag means that font is being used for a bullet rather than actual text. Probably a text level somewhere uses a custom bullet specced with this font. Each content or text placeholder can have up to 9 text levels, you may hove to create 9 levels using Home>Indent More to find the right one.
Start with the Slide Master (View>Slide Master>the larger thumbnail at the top). Then check each placeholder on each Layout (smaller thumbnails below the Master). Finally, check each multilevel placeholder on each slide, in case this was added with local formatting.
My go-to technique is to unzip the presentation into the XML files and do a find and replace on them. That's the quickest way to replace fonts, which can be tucked away in all kinds of obscure places in a presentation. On a Mac, this takes a bit of preparation to avoid problems caused by the OS. If you regularly create PowerPoint files, it may be worth it to set this up. Here's my article on this: OOXML Hacking: Editing in macOS. Look for the part about using a USB or network drive that is set to not create hidden .DS_Store files. Then use a text editor like BBEdit to do multi-file find and replace operations on the font name.
I have PowerPoint 16.39 on my MacBook Pro. Try to click on PowerPoint in the upper left. Then Preferences, then the Save icon. At the bottom you'll have Font Embedding. If you un-check this option, it should not save fonts to the template anymore.
I would like to create a postscript or pdf figure with enhanced notations, italic or bold Latin characters, and sometimes (regular) Greek characters. How to do that in general?
Let's say I downloaded CMU Sans Serif, a font that has glyphs for all the strange characters I ever want to use. I converted them to pfa with an online tool and copied the files to the path of working directory.
Expectations
Let's say I'd like to produce the following notation somewhere.
What I tried: original
I create a gnuplot script encoded in a utf-8 file (without BOM) with the content
set term postscript eps enhanced "CMUSansSerif" 15 fontfile add 'CMUSansSerif.pfa' fontfile add 'CMUSansSerif-Oblique.pfa' fontfile add 'CMUSansSerif-Bold.pfa'
set encoding utf8
set o "print.eps"
p x t "Label: {/CMUSansSerif-Bold important }{/CMUSansSerif-Oblique note}: ∫⟨α₂ + β²⟩ = äßű"
set o
and executed with the newest gnuplot, version 5.2.6.
What I got
I used a vector graphics editor to open the eps file and relevant part looks like this:
What I also tried
According to Ethan's answer I added adobeglyphnames to the termoptions. It made at least the letters available but other Unicode symbols are still unavailable. The result is:
Question
What went wrong? How could I produce the desired output?
So many possibilities, where things can go wrong: Is the font not suitable for this task? Did I download a wrong version of it? Did the pfa converter do a bad job? Did I include the font files incorrectly? Was there something wrong with the set encoding? Do I use a bad vector graphics editor? Do I have wrong fonts installed and the vector graphics editor tries to use them?
I am afraid that the answer is that in general PostScript is the wrong tool for this. If it is at all possible for you to work with PDF output instead, I suggest you do that. It is even possible the resulting PDF file can be translated to a PostScript file by standard tools (e.g. pdf2ps). That is likely to work if the non-ascii characters are limited to Greek and other relatively common symbols but I don't know how much of the full unicode tables are covered by those standard tools.
If you really need to produce PostScript with additional unicode characters directly from gnuplot, you can find full instructions and sample character encoding tables in the gnuplot distribution files:
.../term/PostScript/unicode_maps.README
.../term/PostScript/unicode_big.map
.../term/PostScript/unicode_small.map
I am not familiar with the online tool font conversion you used but probably it failed because it did not have, or at any rate did not use, suitable character encoding tables for the desired conversion.

One other thought. There are two ways that a *.pfa font can encode unicode characters that are common enough to have a name assigned by Adobe for use in PostScript. (1) It may use generic names like uni0439 for Unicode code points. (2) It may use Adobe-specific names from the list here:
agl-aglfn glyph list
When selecting PostScript output from gnuplot you can tell it which of these two conventions is used by the font you provide. The default is "noadobeglyphnames".
set term postscript {no}adobeglyphnames

(recipe for using "set term pdfcairo")
Font handling is unfortunately system-specific, so I cannot tell you how to install or configure fonts on all your target machines. I will show you a procedure that works on a linux desktop that uses the fontconfig utilities for system font handling.
Create directory /home/share/fonts/CMUSans
Add this directory to the search list in file /etc/fonts/local.conf
Copy *.ttf files into this directory from the CMU Sans Serif zip archive you link to in your original query. The system fontconfig system tools should now be able to find these fonts. By inspection they self-report as "CMU Sans Serif"
in gnuplot (tested with version 5.2.6)
set term pdfcairo font "CMU Sans Serif,15"
set output 'enhanced_utf8.pdf'
load 'enhanced_utf8.dem'
convert output pdf file to PostScript with the following command
pdf2ps enhanced_utf8.pdf enhanced_utf8.ps
Screenshot of the result is shown below
It seems that CMU Sans Serif doesn't contain the UTF-8 characters you are asking for. Check the font with a font editor like Birdfont. Although the webpage shows symbols you want to use, the font itself does not contain them. However, your browser may show symbols, but they are just fallback representations from other fonts.
I wrote a script which parses information from PDF files and outputs it to HTML. It's written in Python, using pdfminer.
On some text segments, the font style can have semantic significance. For instance: bold, italic and color should trigger different behavior. Pdfminer provides scripts with the font name, but not the color, and it has a number of other issues; so I'm working on a Swift version of that program, using Apple's PDFKit, to extract the same features.
I now find that I have the opposite problem. While PDFKit makes it easy to retrieve color, retrieving the original font name seems to be non-obvious. PDFSelection objects have an attributedString property, but for fonts that are not installed on my computer, the NSFont object is Helvetica. Of course, the fonts in question are fairly expensive, and acquiring a copy just for this purpose would be poor form.
Short of dropping to CGPDFContentStream (which is way too big of a hammer for what I want to get), is there a way of getting the original font name? I know in advance what the fonts are going to be, can I use that to my advantage?
PDFKit seems to use the standard font lookup system and then falls back on some default, so this can be resolved by spoofing the font to ensure that PDFKit doesn't need to fall back. Inspecting the document, I was able to identify that it uses the following fonts (referenced with their PostScript name):
"NeoSansIntel"
"NeoSansIntelMedium"
"NeoSansIntel,Italic"
I used a free font creation utility to create dummy fonts with these PostScript names, and I added them to my app bundle. I then used CTFontManagerRegisterFontsForURLs to load these fonts (in the .process scope), and now PDFKit uses these fonts for attributed strings that need them.
Of course, the fonts are bogus and this is useless for rendering. However, it works perfectly for the purpose of identifying text that uses these font.
I want to create plots with Gadfly in Julia programming language using a specific font style (e.g., Avenir Next Bold) of a local font (Avenir Next) on my Mac. It works for the standard font style in the case of an standard histogram example:
using Gadfly
plot(x=randn(2000), Geom.histogram(bincount=100),
Theme(minor_label_font="Avenir Next",
major_label_font="Avenir Next",
key_label_font="Avenir Next"))
Yet when a specific font style such as "Avenir Next Bold" is used the default font is applied instead of the provided one. The Avenir Next fonts are saved as a "container" in a ttc format. I tried to convert the ttc file into single ttf files for the font styles and to call the exact paths where the files are located. Both don't work.
I think this is a case of getting the font name exactly right.
(I used HeavyItalic because it's easier to tell if the correct font is chosen.)
It might be that you have to use the PostScript font name, although I'm not sure why that would be, unless deep down in Cairo that's how fonts are accessed... ?
You can get the PostScript names (if that's what they are) by looking at a font manager. For example, FontBook shows them on the info panel:
I would like to know how to extract the metadata of an otf file. For example :
chrono number of the glyphs (ex: 001, 002...)
associated unicode in hexadecimal
etc..
Applications like "Font Examiner" can do it :
Font Examiner
Thanks in advance
If this were my problem I'd probably want to solve it using as much public and/or open source code as possible.
For example, you can use the FreeType library (which apparently compiles for both Macintosh & iOS to load the .otf font, then you can get the metadata off the loaded face (e.g. the num_glyphs attribute in FTFace_rec).
If you can load the font into a NSFont or UIFont instance, you do have access to a numberOfGlyphs and a coveredCharacterSet property (the latter shows the characters a font can render).
