About the mistakes with the names in vanilla. There are several female names that are used in descr_names with an accent while in names.txt are used in a short form. For example:
in names :
There are several others. I recommend you do a search with tornnight`s name verifier:
Also, in vanilla BI the alemanni(the whole list of names) is mentioned 4 times! And the 4 lists are identical.
And three names might have slight issues in BI:
Adalbert is mentioned for one of the alemanni lists iirc with a space after it in descr_names.
Hujr_ibn al_Harith is lacking the _ after ibn in descr_names_lookup
Yabgu Roila also lacking the _ between the two words in descr_names_lookup
The lookup file might not be used, but I`ve mentioned it none the less.
