Dealing with unicode

[Fabian via Digitalmars-d-learn]

I'm trying to add support for unicode to my app in D and having 
issues.

string str = "Pokémon No";
writeln(str);

this outputs:
Pok├®mon No

what I want to do is change the funky character such that the 
string reads:
Pok\u00e9mon No


as \u00e9 == é
how can i do this in D?
