first of all thanks for your fast response.
I've looked in a dictionary, but there is no other word than "Umlaute".
However, I am talking about German ü, ä, ö.
Example: "Sie verfügen über ..." is shown as "Sie verf��gen ��ber", when doing y search / query.
I have checked the wp-config and the themes character-config in the header.php. Everything seems to be configured correctly.
Also in usual posts the ü, ä, and ö are shown correctly. So it's from my point of view not an issue of the theme or the WP installation.
Only in the list (page) of Ultimate WPQSF results this issue appears.
Would be great, if you have any ideas how to solve that.
Do I have to add "char: utf-8" anywhere in one of the plugins php-files?
Thanks and best regards,
