@cyberfox1 without any further information its not possible to help you. Paste your filetypes.common to a pastebin and put a link here, plus the usual version of Geany and system you are on from the top of `Help->Debug Messages`
It doesn't sound like you have been able to help anyone.
Whilst its tempting to yell at Ubuntu to "fix your [expletive deleted] font"
You need to get it into your head it is ALL fonts and Geany is currently an unusable product.
