The other bug is that the X keycodes don't match up with unicode characters. What's more is that the keycode for lowercase `a` and uppercase `A` is the same. This complicates things a bit.

There is a keyboard for Android called the Hacker's keyboard that allows you to even send PgUp, PgDown, Home, End, Ctrl, Alt, Fn, etc. keystrokes to the apps. Do you think it would be possible to capture these keystrokes and send the directly to KDE? (ie: not the actual letter but the keystroke itself). That would be better than this approach but I'm not sure if it's possible (because some symbols in the android are not keys individual keys in a regular keyboard). 

If this is not possible (and we stick with sending just letters), it would be nice to allow to send special keys (Ctrl, Alt, etc.) anyway if we have a keyboard on Android that supports it. The same code that will allow you to send those keys will probably allow you to send backspaces and other non-letter keys as well.
