Function Initiate Unicode UTF-8 Encoding (MBCS)
ASCII [ESC] + M
Hexadecimal 1BH 2BH 4DH
Decimal <27> <43> <77>
Description The [ESC] + M command will put the printer into UTF-8 character
encoding mode of operation. If you wish to access characters above
255, You must select a Unicode encoding such as UTF-8.
You must select a downloaded font, as described in this section, before
issuing this command.
UTF-8 uses a Multiple Byte Character Sequence (MBCS) to identify the
desired Unicode character. This encoding method is less straightforward.
This method uses unique bit sequences at the MSBs of a byte to
determine its location and meaning within the MBCS encoding. See the
table below for more information.
NOTE: All information sent to the printer must now use this encoding,
even for non-print commands.
