Well, actually this is what I did to create it: Look into the charmap if it

someone can hint me to an existing API?


You won't need much of a parser, just look at the lines between CHARMAP
and END CHARMAP.

Hmm... actually there is a reader for charmap files (locale/programs/charmap.c).
Anyhow I think I found a smarter way to do this by adapting the MB_CUR_MAX macro.
