A good question! Let me see... does [\p{L}] work? Ah yes, it does. So

requires work in pcre_compile.c.

It *should* just be "letters, digits, and underscore", but I am not sure
exactly how Perl 5.10 treats it. Some experiments are needed to check
this, because the ideal is to be compatible with Perl.
