Mac and character set

[mikme at tiscali.se (Mikael Metz)]

After recommendation of some here I checked out Eclipse and really like 
it. I am using Mac OS X.
However, I have one problem with it.
It cannot handle keyboard input from characters in Mac's 'upper ascii' 
(or whatever it's called), that is non-english characters like å, ä, ö.
If I want to write Swedish in a comment, or give a method a Swedish 
name, it seems not possible to write it in Eclipse (if I import a 
project or file written in another editor, these characters display 
fine.

I tried  changing the encoding in Eclipse, but no difference.

Is it SWT that somehow does not fully understand keyboard input from a 
Mac on those characters? (as I guess SWT handles events too?)

Did not really find anything about this on the eclipse.org site.

grateful for help

who does not know anything about SWT  :-)

addendum: using such characters in a file that is edited on a Mac and 
well as other environments (and vice versa) is not recommended anyway, 
as it comes out as garbage on the other machine.
