We were looking at the Tcl regex lib (I think Owen maybe said it was
based on Mark's lib?) - and wondering about this issue. We were
worried about having to convert the regex and the search string
to/from UTF8, since that seems to make things slow. But maybe a slow
facility is better than none, and we could fix it later. No decision
reached.

The Perl one looks viciously difficult to extract from Perl. I haven't
looked at the ICU engine, I'll ask Owen about it, I know he's looked
at ICU in general.
