UTF-16
UTF-16 is the most straightforward way to access characters above 255. UTF-16
essentially sends two 8-bit bytes that form a 16-bit address to access the desired
character. Basic UTF-16 does not define the byte order. If you wish to use UTF-16 and
allow the printer to determine the byte order, you must send the byte order mark
(0xFEFF) before you send any characters. To prevent loss of byte order
synchronization, you should periodically send the byte order mark to resynchronize the
printer with your application. If UTF-16 is selected, all data sent to the printer must be
16 bits. All commands and command parameters are also 16 bit, however only values
between 0 and 255 are valid. Extended addressing uses surrogate pairs to encode
values above 0xFFFF.

Note: wwww = uuuuu – 1 and uuuuu may not be larger than 10000

UTF-16
With UTF16 values from 0x0000000000 to 0x0000D7FF and 0x0000E000 to
0x0010FFFF may be represented Values from 0x0000D800 to 0x0000DFFF and above
0x0010FFFF are not valid and in fact are not valid for any characters in Unicode rev 5.0
regardless of encoding.
UTF-16BE uses the big-endian method of sending the two bytes. This method sends the
high byte first and then the low byte. It is not required to send the byte order mark
