Well this is subjective. BUT maybe it isn't shown correctly on your mashine. The font is called "Palatino Linotype" and it's a beautiful (if shown correctly like in my screenshots) and capable font for several languages.

Solutions:
1.) try to install this font by double click on the pala.ttf and palab.ttf file in the font folder of my mod. Then click install in that window
2.) delete the font folder in my mod and ignore that Latin, Greek and others are now extremely ugly
3.) Find another capable font in a .tff file which looks good and works with the languages and tell me in the commentary section. I will look into it and maybe replace the current one with your one.

Going back to vanilla font is not possible because this one is able to show the new characters I have added for a better representation of several languages like Latin and ancient Greek.
