Thanks for answer. I always have more generic question about string
coding conversion.
What if I have some bytes and know its charset/coding and want convert

I search for such functions and also how get list of coding names for they.
Any point to existing code or ather help welcome.
'info elisp' take a few knowledge in this area.
