Hi Klaus,

Found a bug in VDR-1.5.5 in non-UTF8 mode. In any text field, when the cursor is on an uppercase non-ASCII character like ÄÖÜ, the up/down key jumps directly to A.

The core problem is that the non-UTF8 version of Utf8ToArray sign-extends chars to uints, turning the ä of the allowed chars into 0xFFFFFFE4, while the towlower() of the edit control changes the Ä into 0x000000E4, which is then not in the list of allowed characters. Lowercase works, since here everything stays sign-extended.

The attached patch changes Utf8ToArray to properly extend chars as unsigned.

Cheers,

Udo
