Hi,
I get syntax errors in a grammar when trying to use '\uXXXX' - is this
not supported? How can I specify explicit character codes ?

Thanks, I commented on the bug.

I had hoped this was fixed - the latest documentation does not mention
that \u is not supported - an older version of the documentation stated
that it wasn't. OTOH, the new version of the doc does not state that it
is possible either...

Regards

Hi,

i can find this in the current 1.0.1 docs:
Quote:

The following standard Java notations for special characters are allowed: \n, \r, \t, \b, and \f. We currently don't support quoted unicode character notation, as \u123.

Sorry for the noise.
