New language?
 

A friend asked if there was anyway to be able to change the language he
reads in game to Italian, I looked around at the fonts and figured it can't be too hard to make this however, the Fontbuilder is rather confusing to me. Is there anyone who could help me understand how to use this program a little better? I was planning on making a new Truetype file for this, then editing a currect font xml file. Any suggestions or help on this would be greatly appreciated!

You can't change the language by changing a font.

Translator, not Truetype
 

Italian uses primarily the same characters that the English language uses, with the exception of some diacritical marks. However, an Italian-speaking individual would be able to infer these marks through context if they were not included with very little loss of comprehension.

However, as the previous poster stated... this doesn't help whatsoever if the language itself is not translated. You can't take the word "time" and correct a font to get "tempo." You need to translate each sentence not only for vocabulary but for sentence structure and idiom and on and on and on.

So the short answer is no, you can't tweak a Truetype and talk to Tuscany. Torry. Er, sorry.

Ok, think I've confused myself with it.
Will changing the .xml files work.. or can you suggest a way to do this? Thanks!

You can't. The game itself has to support that language already.
