Hi Peter,

The support of international characters in Amaya is quite complex.
Of course we could switch to ISO-8859-2 charset to support another
subset of European languages, but the right general solution is to
handle Unicode characters.
This implies 3 steps:
1- Replacing the handling of 8 bits characters by Unicode functions.
   Due to external constraints, sometimes Unicode characters must be
   encoded as UTF-8 strings, sometimes they must be encoded as
   So the adaptation of the code is not easy and adequate conversion
   functions must be developed.
2- We need also to write displaying functions that'll find for each
   character the right font and the right glyph within the font.
   Theses functions depends on the platform (Windows or X-Windows).
3- Then several input methods should be added to the Amaya code.

Just the step 1 is quite finished now.
