Reworked unicode support

[derSteFfi]

afaik we are using utf8-cpp since b668ee9

That commit only introduced it to the packaging dump and there's still plenty of use of wchar_t.

[derSteFfi]

~/ja2-strat (git)-[master] % grep -r wchar_t * | wc -l
3648

OK, that's a lot.

edit:
a bit better if we do not count binary matches:

~/ja2-strat (git)-[master] % grep -rI wchar_t * | wc -l
3260

Rechecking a year later: it indeed appears not to be needed any more (as in extra changes), especially since the new android test saw no issues (#228 ). Perhaps something from Omnigraphical's Android patchset (#435) would require it, but we can handle it then. This one is too vague, while wchar_t and original bugs are not a problem any more. Closing ...
