i have done some debugging and i tried to convert the special characters 
in class.tx_commerce_attributeeditor.php at line 106:

$config['label'] = htmlentities($aData['title']);

this fixes the errormessage, BUT:
in the form the converted ü of the word "stückpreis" is converted to 
ü by the function htmlentities at first. all right.
but then when the form gets rendert the & is converted once again and so 
i get ü in the html output which avoids that the special 
character is displayed correctly.

anyone has an idea of fixing this?
