Thanks a lot , but I don't think it is simply a matter of pure ascii 
(7bit character) or extended ascii (8bit character)
since:
- e grave (dec 232) and e acute (dec 233) for instance, are accepted, 
and a grave (dec 224) and u grave (dec 249) not.;
- all the source file of ANTLR I saw have the option "charVocabulary = 
'\3'..'\377';"

Jean-Claude.
