Cyrillic isn't an issue.

Lithuanian, Turkish and Azeri are the ones with the biggest issues.

There is a bunch of non-simple mappings for Latin, Armenian and Greek, 
but they are not language dependent. There is six conditional ones which 
are all Greek.

So if you are not dealing with these languages (even if you are, a 
simple replace should be easy to do for most), you should be fine with 
the simple mappings supported by std.uni.
