The only Croatian person is Marko Nikolić, but with no accented letter. Could you also add Joško Nikolić (the Croatian translator) and Volkan Gezer (the Turkish translator) to the authors file as well? The file name (in all capitals) is AUTHORS.
It is very great so that you have to accentuate Marko's name at the message. But you use "straight quotes" or “smart quotes”. And Van Schaik's name is credited under the surname (and not on the particle). Here is the sort that you want for the section: va. South African and Namibian names in Dutch should have been sorted on the prefix (particle), but not in the surname.
Vainer, Moshe Valoska, Hleb Valtonen, Hannu Vance, Carroll Vanek, Tomas van Schaik, Carl (Note that this is on a letter by letter sort.) Vaughn, Charles
