Please DON'T move to PCRE. "Outside world standards"? There are so many. There are two important things to know about PCRE: (1) it is a popular open source regexp library for Perl-style regexps, (2) because of that, it is prone to truly horrendous performance problems. There are alternatives, such as re2, https://github.com/google/re2 , which are not subject to PCRE's intrinsic performance pathologies. As it happens, re2 supports *? +? and ??.
Can you share some examples of PCRE's bad performance? Pierce
