If you need to perform this kind of operations on Unicode strings 
in D, you can call normalize (std.uni) on the string first to 
make sure it is in one of the Normalization Forms. For example, 
just appending .normalize to your strings (which defaults to NFC) 
would make the code produce the "expected" results.

As far as I'm aware, this behavior is the result of a deliberate 
decision, as normalizing strings on the fly isn't really cheap.
