Unicode characters on ZPL printer

Question

I have the task of re-designing a system to print shipping labels, using a networked Zebra GK420T. I have been able to send ZPL print jobs to it perfectly fine, but I cannot

You can replace character that greater then one byte to UTF-8 hex string with underscore like "ћ => _D1_9B". Sample code below;

 var zpl_code = "^XA" +
        "^LH100,150" +
        "^CWT,E:TT0003M_.FNT" +
        "^CFT,30,30" +
        "^CI28" +
        "^FT0,0^FDTesting 1 2 3^FS" +
        "^FT0,50^FDДо свидания^FS" +
        "^FT0,100^B3^FDAAA001^FS" +
        "^XZ";
        var unicodeCharacterList = zpl_code.Distinct()
            .Select(c => c.ToString())
            .Select(c => new { key = c, UTF8Bytes = Encoding.UTF8.GetBytes(c) })
            .Where(c => c.UTF8Bytes.Length > 1);

        foreach (var character in unicodeCharacterList)
        {
            var characterHexCode = string.Join("", character.UTF8Bytes.Select(c => "_" + BitConverter.ToString(new byte[] { c }).ToLower()).ToArray());

            zpl_code = zpl_code.Replace(character.key, characterHexCode);
        }

This code set zpl_code variable to below output

^XA
^LH100,150
^CWT,E:TT0003M_.FNT
^CFT,30,30
^CI28
^FT0,0^FDTesting 1 2 3^FS
^FT0,50^FD_d0_94_d0_be _d1_81_d0_b2_d0_b8_d0_b4_d0_b0_d0_bd_d0_b8_d1_8f^FS
^FT0,100^B3^FDAAA001^FS
^XZ
