[antlr-interest] Acentuation in grammar

[Luciana Nunes Leal]

Hi,
 
My grammar can contain characters like á, é, í, ó, ú. 
 

When my grammar is like below and I run antlr.Tool, I see the error below.

 

grammar:

CHARACTER : ('a'..'z'| OxE1 | OxE9 | OxED | OxF3 | OxFA )+ ;

 
error:
ANTLR Parser Generator   Version 2.7.5 (20050128)   1989-2005 jGuru.com

error: Lexer rule OxE9 is not defined

..\src\lnc.g:99:64: warning:Alternate omitted due to empty prediction set
Exiting due to errors.
 
Is there another way that I can permit acentuation?
 
Thanks, Luciana.
