proper unicode support in C++ was pretty hard work as far as I remember; I started using ICU, which is the *complete* solution, so I suggest we try continue on that. ICU also has regexp support, so maybe PCRE is redundant?
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
Note: Implementation should also be updated to support unicode/wchar_t
Can you look into this if you have some spare time to kill and you need something to do. ;)
