I don't know if I'll be able to go on with that. When I was coding in smalltalk and at the very beginning of java I was happy to use the full power of my speaking language in my programs but I had to give up my accents because most tools were unable to handle them.

Now that (on linux) most tools deal correctly with UTF-8, I try again, at least on programs that I'm sure I won't share with people not understanding French (for example French MMORPG). Time with tell but I don't take this risk at work.
