It supports utf-8 and Unicode properties. Don't ask me more about this 
because I know very little about Unicode :)

It's slower and doesn't support some patterns supported by pcre.

PCRE benefits:

- it's faster

- has more advanced regular expressions

- supports partial matching (using the pattern ^ab against the string a 
the match fails but pcre knows that there is a partial match so adding 
more characters may lead to a match), see 
http://www.barisione.org/eggregex/eggregex-eggregex.html#egg-regex-is-partial-match

- DFA matching (matching <.*> against <a><b><c> you get <a>, <a><b> and 
<a><b><c>)
