Best approach to handle accented letters

[Alfred Newman via Digitalmars-d-learn]

Hello,

I'm getting some troubles to replace the accented letters in a 
given string with their unaccented counterparts.

Let's say I have the following input string "très élégant" and I 
need to create a function to return just "tres elegant". 
Considering we need to take care about unicode chars, what is the 
best way to write a D code to handle that ?

Cheers
