[antlr-interest] Problem with "Unexpected char" (Antlr 2.7.5)

[VAUCHER Laurent]

Perhaps you simply don't have a rule that matches it.
 
Do you have a 'catch-all' rule of the style:
 
LOST_CHARACTER : . ;
 
at the end of all rules?

Thank's Dominik for your response.
 
I think the character '|' is \u007c. I don't know what I'm doing wrong.
 
Any help?

	Hi Jose,
	 
	Just a thought:
	Perhaps the '|' is not in the range of your charVocabulary definition: charVocabulary = '\u0000'..'\uFFEE';

		Hi, I don't know how to do to recognize the character '|' in the lexer. 

		In the lexer I have:


			class CobolLex extends Lexer;
			options 
			{ 
			k=1;
			charVocabulary = '\u0000'..'\uFFEE';
			caseSensitive=false;
			caseSensitiveLiterals=false;
			testLiterals=false;
			exportVocab=CobolLexVocab;
			}
			 

		The error:

		Know anyone what's the problem?.
		 
		Thank's in advance.
