[Takekazu O. <tak...@gm...>]

see "Scanning Unicode Characters" in  http://www.antlr2.org/doc/lexer.html

Re: [Springnet-developer] BUGS Spring.Expressions reject UNICODE character

[Mark P. <mpo...@in...>]

Hi, 

I made the change to the .g file but get this exception when running the
test 

antlr.TokenStreamRecognitionException: expecting ''', found '漢' 

All other tests still pass though. Can you help me to construct a unit test
to pass? Thanks for the feedback, I also feel we should support unicode.

This is JIRA issue
http://opensource.atlassian.com/projects/spring/browse/SPRNET-740
