I've been trying to get ZPL working with a combination of ^FH and new lines. For some reason when I use the following code
^FH\^FD<RECEIVERNAME>\&<RECEIVERSTREET>\&<RECEIVERHOUSENUMBER>^FS
It ends up as
<RECEIVERNAME>&<RECEIVERSTREET>&<RECEIVERHOUSENUMBER>
I cannot seem to figure out how to stop ^FH from converting the new line to a symbol.
Hex for a new line is 0a, and hex for carriage return is 0d.
Neither of them work with http://labelary.com/ so I'm guessing that they are not supported for what you are using them for.
Line break characters (0x0d and/or 0x0a) like any other nonprintable characters are not supported in the commands ^FD, ^FV and ^SN, as stated in the ZPL Programming Guide. See the description of the ^FD command for reference.

I'm having some issues with the using line feeds / carriage returns in ZPL with my Zebra LP2844z in CUPS (Raspberry pi).
According to Zebra's documentation and example, I just need to enable hex command using the FH switch, and use the hex encoded "_OD_0A" for a carriage return.
https://www.zebra.com/us/en/support-downloads/knowledge-articles/including-carraige-return-line-feed-in-qr-barcode-using-zpl.html
This example works fine until I try and add more lines:
^XA
^FO100,100
^BQN,2,10
^FH
^FDMM,B0024First Line _0D_0A Second Line _0D_0A Third Line _0D_0A Fourth Line _0D_0A ^FS
^XZ
This results in the following generated QR code:
And contains the following text:
First Line
Second LinTHIRD LINE UFOURTH LINE U
Something was going wrong at what appeared to be around the 24th byte which I realised coincides with the bytes "represented" (as mentioned in the documentation).
I then increased this further and found that I need to change the bytes representation in the "FDMM,B0nnn" switch for every byte in the string. If I increase it over what appears to be an arbitrary number (let's say 100 bytes) it messes up the QR code text again.
That might work for static text where I know the length of the string in bytes. However, I want to create these barcodes dynamically and each string will have a different byte length.
How can I handle it?
I was having the same problem. This is what I have done:
^XA^MUM
^FT50,50^BQN,2,1^FH_^FDMM,AFirst Line,B0002_0d_0a,ASecond Line,B0002_0d_0a,AThird Line,B0002_0d_0a,AAll the lines that you need^FS
^MUM^XZ
This is the document that I have used to know what I need to do:

I hope it will be helpful for you also.
So i have an object with a textarea property which i am giving a text with xwiki syntax in it to make a line break according to the documentation
XWiki Syntax 2.1: New Line/Line Breaks. Below is the text I am uploading.
=Beschreibung Ablauf der Notfallübung=\\==Planung==\\Um die Sicherheit im Brandfall zu erhöhen veranstaltet ...
The problem is, that the first heading gets formated right but everything after the line breaks looses its formatting. How can i prevent that from happening?
I changed the double backslash line break (\\) to a simple line break (\n) and it worked accordingly. Still don't know why it didn't work though. Not a good answer for the question I know but an working alternative.
Placing an ASCII 10 (0A) character somewhere inside of a segment of an HL7 message to represent a new line character. Is this valid?
From what I can see it is recommend to use \X0D\ or \X0D0A\ to represent a new line character for plain text format HL7. Is using just the 0A ASCII character explicitly invalid HL7?
To respond to the question "Is using just the 0A ASCII character explicitly invalid HL7?":
The character 0A is not mentioned anywhere in the HL7 specs as being special.
Extract from the HL7 2.5 US specs:
2.5.4 Message delimiters
In constructing a message, certain special characters are used. They are the segment terminator, the field
separator, the component separator, subcomponent separator, repetition separator, and escape character. The
segment terminator is always a carriage return (in ASCII, a hex 0D). The other delimiters are defined in the
MSH segment, with the field delimiter in the 4th character position, and the other delimiters occurring as in
the field called Encoding Characters, which is the first field after the segment ID. The delimiter values used
in the MSH segment are the delimiter values used throughout the entire message. In the absence of other
considerations, HL7 recommends the suggested values found in Figure 2-1 delimiter values.
Strictly speaking this would mean that you could use the character 0A just as any of the characters other than the 6 previously mentioned.
<end of "formal" reply>
That being said, I concur with Dale H. that you should better stay away from using this character in the content of an HL7 message. Since most editors (except old-fashioned Notepad on Windows) will display this character as a new line, you might unwillingly think that a segment was truncated or malformed. And I've had at least one instance where the interface engine indeed handled that character as a segment termination (which in itself is invalid, and the interface engine build was modified to not do this anymore).
So better avoid this. But in situations where you don't control the output, it doesn't seem to be a formally disallowed character...
Linefeeds (0x0A) are not allowed in HL7 messages. If you edit messages with notepad, wordpad and many other text editors, they will convert carriage returns (0x0D) to CR/LF (0x0D 0x0A) and if you save, you now have a corrupt HL7 message. Avoid LFs (0x0A).
If you only send 0A then there is no way to determine that you wanted ASCII 10/line feed and it would be assumed you wanted a zero and an A.
Standard HL7 with the escape character being a \, then yes the recommended way would be \X0A\. The \X representing the start of hexadecimal data, followed by two-character hexadecimal values, ending with a \.
That being said, if you are sending this data to a system then they should be able to tell you what they accept for lines feeds. I've seen systems that use \.br\ or the repetition character ~ to determine a new line. And sometimes they want repeating segments. For example below, each OBX segment is a new line of a report in the system.
OBX|1|TX|||This is line one
OBX|2|TX|||This is line two
I am maintaining a program that outputs ZPL to a label printer. Today, the character sequence ~Ja came in as part of a string to be printed, which is ZPL's "cancel all" command. Needless to say, the label did not print.
Is there an easy way in ZPL to escape a tilde?
You can use ~CT or ^CT to change the tilde control character to any other ASCII character, and then you can print tildes normally. However, the new control character won't be printable. This is probably going to be quite a hassle to maintain.
An example changing the control command prefix to +, taken from page 165 of the ZPL II programming guide:
^XA
^CT+
^XZ
+HS
If your string is represented as field data with ^FD, ^FV, or ^SN, you can use ^FH to encode the tilde in the string with its hex value, 7E.
An example, taken from page 192 of the ZPL II programming guide:
^XA
^FO100,100
^AD^FH
^FDTilde _7e used for HEX^FS
^XZ
Output:
Tilde ~ used for HEX
~ can be printed by replacing to \7E
It seeems like replacing these three characters will allow any key on the keyboard to print fine. I figured this out using ZebraDesigner, printing to a file and seeing what characters they escape.
\ to \1F - do this first or it will break the two below
~ to \7E
^ to \5E
Here is the code in C#
private static string escapeChars(string working)
{
working = working.Replace(#"\", #"\1F");
working = working.Replace(#"~", #"\7E");
working = working.Replace(#"^", #"\5E");
return working;
}
I have a string contain some special char like "\u2012" i.e. FIGURE DASH. When i am trying to print this on console I am getting a '?' mark instead of its symbol. I have an editor where in I can insert the symbol using alt+numpad like alt+2012. In editor it I could see the symbol save it in a xml file and get the value using nodevalue, I get a '?' mark.
To summerize I am facing problem to read extended latin a charset. What i need is When i insert such symbols and read it, i should get something like &#xXXXX;.
Please help!
TIA :)
Simply I have a String inpath = "À";, I want to get its unicode value..like &#xXXXX;
The default console encoding in Windows is some MS-DOS code page and they don't support the character. You can try running chcp 65001 before running the program but you might also need to change the console font as well.
You don't need to do anything you wouldn't do with any other character, as long as you use UTF-8. You aren't doing that in many places. You need to explicitly write in your code to save and read the file in UTF-8, and not rely on the platform default encoding.
