If I shouldn't need a \0, what should I need then? I can't simply replace the entry with "`" because that would mean the unshifted symbol is a grave, which is ALWAYS wrong for a german keyboard layout. " `" would be also wrong, since the un-shifted keypress doesn't produce a space symbol.
Have you actually tried that, or just think it won't work?
