I just caught hold of this thread so sorry if this fix has been mentioned but has anyone suggested the Multi_Key? You can setup Xmodmap to configure a key as the multi_key, right now I'm using the righthand tux (windows) key. What it does is act as a starter key for ascii combinations, for example: multi_key, ", o (typed in sequence) gives an รถ (o with an umlat is that doesn't display correctly). I haven't found a complete list of the multi_key combinations but have found quite a few through trial and error and will be happy to write up what I know if that would help.
Here's a copy of my .Xmodmap: keycode 0x74 = Multi_key keycode 0x73 = Escape keycode 0x31 = Escape keycode 0x09 = grave asciitilde -- Stephen Ball | http://www.stephenball.net "Education is an admirable thing, but it is well to remember from time to time that nothing that is worth knowing can be taught." -- Oscar Wilde, "The Critic as Artist"
