My name is displayed incorrectly on the profile page; My name contains the swedish character 'ö' (latin small letter o with diaeresis - U+00F6). This character is rendered as two squares with a question mark.
Funny fact #1: the name is rendered correctly in the "profile" -> "edit" page.
Funny fact #2: the name is correctly rendered for a (very) short time just after loading the profile page. It looks like it is using a different font for a very short period of time, and once it switches to the "correct" one, the name is no longer rendered correctly.
