Accents in LaTeX?

[Magnus Therning <d94magth@isy.liu.se>]

I can't get the national characters to work in LaTeX! For some reason I
can't make the \aa, \"{a} and \"{o} to work, but I can make the other
ones work (\"{u}, \ae, etc.)
I am doing anything wrong? Is there some .sty-file I've forgotten to
include?
I'm using LaTeX2e layered on TeX Version 3.1415 (C version 6.1)

(I just installed all I thought I needed from the Debian 0.93R6 tree)

I found this in the .log-fil
Missing character: There is no ^^e4 in font cmr12!
Missing character: There is no ^^f6 in font cmr12!
Missing character: There is no ^^e5 in font cmr12!

Please help me.
