Rép : [antlr-interest] extended ascii chars

[jcdur]

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 !
- and all the source files of ANTLR I saw have the option
"charVocabulary = '\3'..'\377';"

Hi, somebody recently asked this I think.  antlr.g itself only accepts
latin char until you alter antlr.g to say 0..255 instead of 0..127;
then rebuild.

Sorry about that...

Can somebody explain me why I got an error because of the 'à' in
the comment when running "java antlr.Tool" on the following file:

options
{
	language = "Cpp";	
}
/* Eléments lexicaux: */
class Lex extends Lexer;
options
{
	charVocabulary = '\3'..'\377';
}
// Noeuds ne correspondant pas à des terminaux:
tokens
{
	// utilisés dans l'AST d'un ao:
	Foret;
	Arbre;
}

ENTIER: ('0'..'9')+;

...

I have the same pb when this character or 'ù' appears in rules.
Thanks,
Jean_Claude.
