File kbd-unicode-fxxx.patch of Package kbd.29031
Disable characters >=U+F000. These do not work properly.
Explanation from Alexey Gladkov:
The kbd value is unsigned short [1] and take a look how kernel gets
a type [2]. The last bytes are occupied by type.

The problem in the kernel. In the kb_value there is no room to store such
values.
