Print characters with an acute in ZPL

Question

If I send the ZPL commands below to a Zebra printer, it prints AmitiÙ:

^XA
^FO50,20
^CI7
^A0N,25,15
^FD
Amitié
^FS
^XZ

Note that the file encoding is ANSI.
Note the use of the ZPL command ^CI7 (7 => Single Byte Encoding - France 1 Character Set).

On the other hand, if I send the ZPL commands below to a Zebra printer, it prints Amitié (which is what I actually need to get):

^XA
^FO50,20
^CI28
^A0N,25,15
^FD
Amitié
^FS
^XZ

Note that the file encoding is UTF-8.
Note the use of the ZPL command ^CI28 (28 => Unicode (UTF-8 encoding) - Unicode Character Set).

Do you know what's wrong in the first case?

Thank you for helping.

Use UTF-8 by placing a ^CI28 command at the top of your ZPL template, eg

^XA
^CI28
^CF0,80
^FO70,40^FDavión^FS
^XZ

According to the programing guide document from Zebra ^CI using 7 will get you Code Page 850 with some specific character replacements. When you say you had the file encoded in ANSI, I assume you mean Code Page Windows-1252 or ISO-8859-1 (latin1).

The character é in Windows-1252 and latin1 is #00E9, but that's Ú in 850; you would want #0082 for é in 850. Using ^CI7 you could apparently also get an é with #007B since that's one of the specific character replacements made with that command.

Using UTF8 (with ^CI28) is probably the way to go since it's widely supported and understood, but note that you could also try ^CI27 (which may work even if you have an older version of the Zebra firmware that doesn't support ^CI28) and that should get you code page 1252. If that doesn't work you'll need to encode your text using code page 850.

If you copy and paste your first example into a text editor that can convert between UTF-8 and ANSI (Notepad++) you'll see that the first example is encoded as

^XA
^FO50,20
^CI7
^A0N,25,15
^FD
AmitiÃ©
^FS
^XZ

And this will be cause problems with your ZPL when rendered. See online examples for ANSI and UTF-8.

To fix this you could encode your values first (for example as hex and then prefix with ^FH)

Here is what I did to be able to do that:

Define UTF-8 charset using ^CI28
Use Swiss unicode font. For my case I only needed to encode on a single line and I didn't want to change anything else on the document or printer settings. For that I used ^A@N,44,30,E:TT0003M_.TTF. If you want to define the font for the whole document check the first link below.
Prepared the string to recognize UTF-8 encoding with ^FH immediately before ^FD
Encoded the document to replace non-ASCII characters with their HEX representation:

    private static string ZebraEncode(string text)
    {
        var ret = new StringBuilder();

        var unicodeCharacterList = new Dictionary<char, string>();
        foreach(var ch in text)
        {
            if (!unicodeCharacterList.ContainsKey(ch))
            {
                var bytes = Encoding.UTF8.GetBytes(ch.ToString());
                if (bytes.Length > 1)
                {
                    var hexCode = string.Empty;
                    foreach(var b in bytes)
                    {
                        hexCode += $"_{BitConverter.ToString(new byte[] { b }).ToLower()}";
                    }

                    unicodeCharacterList[ch] = hexCode;
                }
                else
                    unicodeCharacterList[ch] = ch.ToString();

                ret.Append(unicodeCharacterList[ch]);
            }
            else
                ret.Append(unicodeCharacterList[ch]);
        };

        return ret.ToString();
    }
