META Text Control Byte Reconfiguration

[lwvmobile]

Reconfiguring the Control Byte on META to discard the bitmap sequence and instead use a 4-bit numerical and sequential values 1-15 will allow for a much KISS friendly approach to Meta Text and also allows the expansion of Meta Text to up to 195 UTF-8 encoded characters. See discussion on the M17 Discord for more info. The current configuration uses two sets of bitmaps that don't match in a logical sense and reading them can be confusing.

See Items below, for example:

Control Len: 195; X: 211; K: 195; Meta Type: 00; Meta Text: this is a really long m17 meta text that can know hold up to 195 UTF-8 encoded characters blah blah blah xxxxxxyyyyyyyyyyyzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz

Can't we start counting from 0? For 16 chunks, the first byte would be 0xF0, 0xF1, ..., 0xFE, 0xFF.

[lwvmobile]

Yeah, I suppose you could start counting at zero, and that would add an additional 13 UTF-8 encoded characters, bringing the total up to 208.

[lwvmobile]

No, actually, because 0x00 would be the starting byte for a singular payload, so it breaks, got to start at 0x11.

[sp5wwp]

You are right, I realized that too late :)
