[antlr-interest] Accentuated chars in brazilian portuguese

[Bart Kiers]

Hi Nilo,

The grammar:

grammar Brasil;

parse
  :  WORD EOF
  ;

 WORD
   :  ('\u00c0'..'\u00ff' | 'a'..'z' | 'A'..'Z' | '-')+
   ;


parses the input "não" just fine in ANTLRWorks.

I'm not really familiar with C#, but for those who are, could you perhaps
post *how* you are testing it? (post a test rig that shows the behavior you
describe)

Regards,

Bart.
