[antlr-interest] Unicode XID_Start/XID_Continue? (And other Unicode properties)

[Joe]

Are Unicode properties supported by Antlr in any way? It would be nice 
to be able to simply lex unicode identifiers as ID : XID_Start 
XID_Continue*
Or would I have to write a script that creates the appropriate lexer 
fragments from 
http://unicode.org/Public/UNIDATA/DerivedCoreProperties.txt ?
