When running AWB general fixes on [[Talk:Günter Blöschl]], it wants to remove the diacritics in |listas=Blöschl, Günter to |listas=Bloschl, Gunter.
Per [[Wikipedia:Categorization#cite_note-2]], removing the diacritics is no longer necessary since the English Wikipedia's category collation was changed to "uca-default" in 2016.
Therefore, please change the WPBiography general fixes so it no longer removes diacritics from |listas= (and update [[WP:AWB/GF]])
If FixCategories still removes diacritics from category sortkeys, please change the general fixes for this too (and update [[WP:AWB/GF]])
This functionality was removed from SetDefaultSort a while ago, so I updated [[WP:AWB/GF]] today.
Thanks!
