I'm migrating from vB 3.8 (ISO 8859-1, latin1). On my forum I have a user called "Diör" but also another one called "dior". The importer is having troubles recognizing both users and reports that "dior" is conflicting with a previously imported user. However everything else is being imported perfectly. If I force the charset to latin1 (instead of leaving it empty) the same problem exists. When the problem disappears is if I set the charset to utf8 but then content of my forum (such as posts and even forum titles) are having strange characters... instead of "ó" I'm getting "A3" (or something like that, just strange characters that I don't know how to enter with my keyboard). What I can do?
