I "find" this a bit strange.
The letter combination "fi" is somehow displayed in a funny way
in my feed (been like that for a long time)

@nprofile1q... This sort of thing happens when a character, in this case the fi ligature, is missing in the selected font so the renderer looks for it in a similar font.
