I don't want to use the foreign-chars-option to keep the category-names within the URL. Is it possible to change the following chars automatically while building the individual directories but not to a simple "_"?
ä -> ae
Ä -> Ae
ö -> oe
Ö -> Oe
ü -> ue
Ü -> Ue and finally
ß -> ss
Everything else (special characters etc.) should still change to "_".
