specuak chars

[Huhu]

Hi, 

can anyone tell how to enter special characters like vowels with accents or 
the spanish "ñ"?

For Linux apps I can enter them by typing a special key sequence, e.g.:
á : [CTRL] [´] [a]

When windows booted directly this also works.  Alternatively it is possible 
to enter the ASCII-number by pressing [Alt].

Well, when I start a windows application with wine none ot the 
possibilities mentioned above work.  

Can anyone tell if there is a way to get around this problem?

Thanks.
