Charset with german Umlaute

Hi,
in most cases i find my solutions all over the net till i have to ask any community. But this time i realy dont know how to go further.

My current problem is, i want to crack passwords with german Umlauts.

For example, lets crack "mörser" - "4eea89ef13ab9faab28b5dac9ce5b633"

I tried to use the de_ISO-8859-1-special.hcchr but it didnt work.

Ive read the manual lots of times and know there is the optin to set HEX chars.

So the missing ö would be 0xF6 but i can not combine al switches corretly.

So if andyone could help me , i would be very happy.

So im looking for :

?l?u?d + öäüÖÄÜß

Thank you very much.
