Random Characters being displayed as symbols in certain Apps.

Hello,
I am looking for a little direction on how to solve this issue. After updating from 13.1 → 13.2, my Firefox, Thunderbird, and LibreOffice will display random
characters as symbols. It is always the same letter, but the letters change (sometimes it is all the m’s, n’s, e’s, …etc). If I highlight the word that has the symbol
and paste it into a text window the right letter is printed. Actually as I am typing this the Title is displaying symbols,

I am using xfce as my window manager (not sure if that matters). Any help would be appreciated.
