Feature request: national encodings support like Shift JIS, CP 1251 and the like

As we all know, the message size in Meshcore is rather limited by length. Doubly so for non-Latin aphabet languages, because it's now using 2 bytes per character, making it even more restrictive.
I know that the text compression is planned to happen at some time, but one doesn't preclude the other, imo.
Would be nice to have that, if it's not too much hassle to implement.

I have a suggestion on how to implement this:
If the first byte is in the range $80-BF, it is not valid utf-8, so we have 64 byte values to indicate other things, like using shift-JIS etc.
The client could then automatically encode using the character set that achieves the fewest bytes, and the receive can see on the first byte, what character set to use.
