ü?

This question is alittle bit out of the ordinary, but I'm just wondering. I'm a bit of a linguaphile. So when I'm programming (with Dev-C++ 4 at home, and Turbo C++ .. uh the version Jesus used... at school), I sometimes get bored and want to use German or any other language I feel like. Well I've tried to use the umlauts (especially the much used ü) and the s-tett (ß) in my programs, but it just comes out as the 'n' that looks like it's an exponent. I'd also like to program in Japanese, but that doesn't seem to be happening because I've tried to use Japanese characters in Dev-C++ and it doesn't even recognize them. I'd probably need something special for the Japanese thing, and I don't think I'm that much into Japanese to go through somethign that difficult, but if there's any way to get around it that's easier, I'd be glad to know.

Also, a really basic code question. In Dev-C++, when I put setw() as anything less than setw(40), it decides to not move at all. I've found that doing something like setw(1)<<""<<setw(9) will give me setw(10) .... as if I normally put it.

Danke!
