[rules-dev] Parameterized Evaluator Definition using \u2282 as parameter

[Wolfgang Laun]

Well, yes, I'm naughty. I've implemented a  parameterized evaluator, using
Unicode codepoint
U+2282<http://www.fileformat.info/info/unicode/char/2282/index.htm>as
a parameter.

But the DRL parser refuses to accept this (as part of square_chunk_data):
  Line 60:59 no viable alternative at input ''
which indicates that the character isn't recognized at all.

I think this happens because, outside of strings, codepoints beyond U+007F
aren't accepted anywhere except
those explicitly specified as IdentifierStart and IdentifierPart. Perhaps
square_chunk_data after an operator
identifier could be made to behave more like a string.

Admittedly, this is esoteric, but it sure does look dazzling ;-)

Cheers
