easyDebian xmodmap woes
 

I thought I knew how xmodmap works, but it is giving me trouble:

Fn + udiaeresis (and other Fn + accented characters) do not work. Here is some part of xmodmap


user@Nokia-N810-43-7:~/easyDebian$ echo $DISPLAY
:1.0
user@Nokia-N810-43-7:~/easyDebian$ xmodmap -pke | egrep 'apost|diae'
keycode 20 = adiaeresis Adiaeresis apostrophe apostrophe apostrophe apostrophe
keycode 24 = q Q 1 2 apostrophe 4
keycode 47 = odiaeresis Odiaeresis equal equal equal equal
keycode 48 = udiaeresis Udiaeresis question question question question

You see I hacked the "q" key, to see what's happening. Pressing Fn+q gives me an apostrophe, but pressing Fn+ä gives me just a plain ä.

Xev shows me
KeyPress event, serial 39, synthetic NO, window 0x1200001,
root 0x3c, subw 0x1200002, time 102980231, (45,33), root: (80,264),
state 0x80, keycode 20 (keysym 0xe4, adiaeresis), same_screen YES,


It seems that there is something magical about the accented chars, but I have no idea what.

Does anybody have an idea?
