Thank you for this clue!
I suppose you meant something like "int bytesInChar =
fl_utf8len1(*str)" instead the " = fl_utf_nb_char(*str, maxBytes)",
aren't ?
Anyhow I made function which works as I want. I won't try to suggest
to add it to fl_draw(), but such function would be a good helper to
use with fl_draw() as Ian said before.

PS Though it seems to me fl_draw(s,n,x,y) is a function that gives
confusing results and it needs thorough docs at least.
