I can't ignore Unicode, because I frequently have to deal with 
Cyrillic alphabet ;) Also Unicode is significantly simpler than a 
set of various incompatible 8-bit encodings (such as 
[CP1251](https://en.wikipedia.org/wiki/Windows-1251) vs. variants 
of [KOI-8](https://en.wikipedia.org/wiki/KOI-8) vs. [ISO/IEC 
8859-5](https://en.wikipedia.org/wiki/ISO/IEC_8859-5)) that were 
simultaneously in use earlier and caused a lot of pain. But I'm 
surely able to ignore the peculiarities of modern Turkish Unicode 
and wait for the other people to come up with a solution for D 
language if they really care.
