You should be able to change antlr/antlr.g in the distribution find the 
part reading:

class ANTLRLexer extends Lexer;
options {
         k=2;
         exportVocab=ANTLR;
         testLiterals=false;
         interactive=true;
         charVocabulary='\003'..'\377';
}

and change the charVocabulary option to:

charVocabulary='\u0000'..'\uFFFE';

Then build antlr according to the instructions.

Cheers,

Ric
