Problem with mapping a key to multiple characters (Unicode + diacritic symbol)

[Pierre-Luc Angles]

Dear Ilya, dear all,

Thanks for your quick and nice answer. So would you recommend me to use, 
for my XKeysymDB file, 7bit characters (e.g. 1888885 to 188888F) instead 
of the last positions of allowed ones (i.e. 8bit characters 1FFFFFF5 to 
1FFFFFFF) or would recommend other positions like private use area 
Unicode (for example F8F5 to F8FF) ?

Thanks again and sorry if my question is too "easy".

Best,

Pierre-Luc
