3.3 UNICODE FRAME
Unlike the previous pixel-based version, MicroGraph LED can manage the Unicode protocol for
displaying non-ASCII 2-byte characters, as for example Chinese, Japanese, Cyrillic, etc.
3.3.1 GRAPHICAL UNICODE FRAME SYNTAX AND COMMAND TABLE
The transmission protocol is completely identical to the Graphical Frame (GRAPH Protocol, see
par. 3.2), with the exception of the transmission of the Data area, where the single characters
must be sent specifying that they are 2-byte characters and ending the string with an ETX Unicode
character (0x2403). Then the ETX (0x03) ASCII character must be sent anyway, just like for other
protocols. It is important to remember to use one of the Unicode fonts (7 or 8).
