That's why you should implementat formatting providers for 
languages that handle such things.

Like in C# you have the CultureInfo class that you can give to 
methods such as ToString, ToLower etc. which will correctly 
handle specific "cultures"

It's one thing D really misses, but is really hard to implement 
when it wasn't thought of to begin with. It should have been 
implemented alongside functions that may change between languages 
and cultures.
