Yes, the implementation based on UTF-8 vs UTF-16 version of PCRE would
only differ on two lines, the UTF-16 -> UTF-8 and UTF-8 > UTF-16
conversion before and after the matching.

I suggest we get started on this with the current version of PCRE, and
hope that entices the PCRE team to work on a proper UTF-16 implementation.

Anyone interesting in jumping on this task?
