I have similar idea to train LLM in Serbian, create even new encoding https://github.com/topce/YUTF-8 inspired by YUSCII.
Did not have time and money ;-)
Great that you succeed.
Idea if train in Serbian text encoded in YUTF-8 (not UTF-8) it will have less token when prompt in Serbian then English, also Serbian Cyrillic characters are 1 byte in YUTF-8 instead of 2 in UTF.Serbian language is phonetic we never ask how you spell it.Have Latin and Cyrillic letters.
