Special Characters

Hi,
I just started to use teachPress for my publication list and it looks already great! Unfortunately, some of my co-authors have special characters in their name, which are not shown correctly on the webpage, but in the system:
– In bib: “Pawe{\l}”; In the admin publication table: “Paweł” (correct); On the webpage “ł, Pawe”;
– Same for “{\ae}“; æ
Is there a fix for that?

Thanks in advance
