Comment(by hakre):

 Since nor mb_string not iconv are non-default, I think there should be a
 fallback regex as well (I should be able to provide one w/o the /u
 modifier). So the function savely behaves on all installs.

 To select which function to prefer, a shootout between all options should
 be run to checkout which one of those performs fastest.
