Considering that (I hope/think) most developers have moved to UTF-8 for=20
their encoding, how useful is it to have a separate (and=20
not-comptible-with-PCRE) regular expression engine still?

I don't know how much oniguruma adds on top of PCRE, but PCRE also has=20
had significant improvements for UTF-8 encoded strings since we first=20
added mbstring/mbregex.=20

Wouldn't a replacement for:

=09mb_regex_encoding($fromEncoding);
=09mb_ereg_match($pattern, $string);

be:

=09pcre_match($patern, iconv($fromEncoding, 'UTF-8', $string));

cheers,
Derick
