[rules-users] Re: rule text internationalization - write rules (drl) in chinese

[Edson Tirelli]

  Dejia,

  This is probably a problem that requires fixing in the rules parser.
Drools uses ANTLR to generate its parser.
  Maybe you can help doing some research about any specific care that must
be taken when working with ANTLR and unicode characters?

  The grammar we currently use is here:

   Thanks,
