Xonfluence: Changed everything in FONT.xml and Language, font works fine, but Font name does not show up in Interface>Skin>Fonts http://prntscr.com/fjsl0v am I missing something else to change so the Font name shows up.
Not sure if it is the same on all skins. But on Aeon Nox Silvo, you need to go to: SkinName/language/english/ then edit the strings.po with the name of the font you are wanting.
Example
msgctxt "#99999" (or whatever number you gave your font ID)
msgid "font name"
msgstr "font name"
