Hi,

On German keyboard layout, when I want to create an e with an accent
(first press the accent key, then the e key), I get the following in
tests/checkkeys:

$ ./checkkeys
The key you just pressed is not recognized by SDL. To help get this
fixed, please report this to the SDL mailing list X11
KeyCode 0 (-, X11 KeySym 0x0 ((null)).
INFO: Text: é

In case there is some encoding error: The line with "INFO: Text:" has
the right symbol at the end, an e with an accent.

Apart from the error message it is quite interesting, that no
keydown-event is produced on pressing the accent key. This would make
that key quite useless for games, wouldn't it?

I have the current hg developer version. System is Xubuntu 12.10 AMD64
on an Acer Laptop.

Best,
Constantin

Does it even have a key code there? It says 0 if I'm reading correctly o_O

Yes. When I do the same actions in xev, the following comes up:

Maybe the keycode is 0 because there is no single key for that letter on the keyboard.

Also, if I comment the call to "SDL_StartTextInput()" out, there is still no event for the first key press. So there is no chance of using that key for a game.
