Problem with replacing faulty characters caused by some improper graphics plugin

Since these are tags, in which mode would i have to try it? Obviously, when only having the file selected, with the tags being visible in a column, that's not the way to do it, because the renam eworks on the file name here, not on the tags inside.

But trying the same with all tags selected inside the metadata panel isn't right either, because that's not where the rename is applied to.

Maybe it's not possible at the time?
