I'd expect the delimiter pairing to work on all "opening punctuation" graphemes. Like this: > /^<:Ps>$/.ACCEPTS("[").Bool True > "q[foo]".EVAL.perl "foo" But if the grapheme consists of a Ps base character plus a combining diacritic, then it matches <:Ps> (identifying it as an "opening punctuation" grapheme), but it doesn't get paired with a corresponding Pe delimiter: > /^<:Ps>$/.ACCEPTS("[\x[308]").Bool True > "q[\x[308]foo]\x[308]".EVAL.perl ===SORRY!=== Error while compiling /home/zefram/usr/perl/pg/EVAL_5 Couldn't find terminator [? (corresponding [? was at line 1) at /home/zefram/usr/perl/pg/EVAL_5:1 ------> q[?foo]?^<EOL> expecting any of: [? Not sure whether this is really a bug, but the mismatch between the <:Ps> regexp and the scope of delimiter pairing is at least less than awesome. -zefram
