Epson 100-88002 manual Function Initiate Unicode UTF-8 Encoding Mbcs All, ESC + M Hexadecimal

Unicode and Fonts

Function	Initiate Unicode UTF-8 Encoding (MBCS)		All
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: Once selected, all information sent to the printer must then use this encoding, even for non-print commands.

Scalar Value

1st Byte

2nd Byte

3rd Byte

000000000xxxxxxx	0xxxxxxx
00000yyyyyxxxxxx	110yyyyy	10xxxxxx
zzzzyyyyyyxxxxxx	1110zzzz	10yyyyyy	10xxxxxx

Function	Initiate Unicode UTF-8 Text only Encoding (MBCS)		All
ASCII	[ESC] + T
Hexadecimal		1BH 2BH 54H
Decimal	<27> <43> <84>

Description The [ESC] + T command will put the printer into UTF-8 Text only character encoding mode of operation. This mode is identical to the UTF-8 mode described above, except commands and there parameters are not UTF encoded. For example the following command would be used to select underline on:

[ESC] W 128.

If true UTF-8 encoding were in effect, the 128 parameter would be UTF encoded to [ESC] W 194 128. With UTF-8 Text only mode this command is simply [ESC] W 128.

Note: This command also applies to graphic data being sent to the printer.

The graphic data is a command and not text. It is not UTF-8 encoded.
