[rules-users] Drools 5.0.0 CR1 : multibyte characters in dsl fails with "no viable alternative at character"

[Edson Tirelli]

    Yusuke,

    I heard about it before. May I ask you please to open a JIRA so that
this is fixed before final?

    Drools 5 uses a completely new DSL parser and this scenario was lost
when the transition was made. The major problem is that I don't know how to
create a proper unit test using japanese characters (although I guess any
multi-byte character would do), so, if you can create and attach a unit test
to the ticket, even better to make sure I have your scenario.

    Thanks,
       Edson
