on windows one could with Alt+235 print ë into (any) textfield. I tried the same on linux and it seems to be not working. Depending on the application the result is different, but never the wanted one.

Is there a similiar combination on linux available?

google about compose key, for example <kbd>Compose</kbd> + <kbd>"</kbd> + <kbd>e</kbd> gives ë. – Eddy_Em Apr 25 '13 at 7:38

To activate the compose key I had to activate it:

1 System Settings > Keyboard
2 On Tab Typing > Layout Settings
3 On Tab Layouts > Options > Compose key

A useful list of compose key combinations can be found here.

Your way isn't common. Common way is to setup compose key in xorg.conf or do it by setxkbmap, for example: setxkbmap -option ',compose:rwin'. – Eddy_Em Apr 25 '13 at 8:55
Does setting it through my way have any impact? Like not working across all applications, or something like this? – philnate Apr 25 '13 at 9:04
No, but your way is very distro-dependent. – Eddy_Em Apr 25 '13 at 10:00

Crtl+Shift+U and then input Unicode hex value. Accept with Enter. 235 decimal is 0xeb so: Crtl+Shift+U and then input eb and Enter.

Works as well. But this isn't as convenient as the other method (brain and hand). Its cumbersome to press the key combination, convert my decimal into a hex and then type it with the other hand. – philnate Apr 26 '13 at 7:00
