Fonts
msgothic_0 is used for Japanese only and is based off of MS Gothic
msgothic_2 is used for English and is based off of PT Sans
If you're developing a translation into a non-English language like Vietnamese and you find that the font is missing characters needed for your language, try renaming the two msgothic_2 for non-English files over the PT Sans ones. These are based off of Deja-Vu Sans which has support for more languages than PT Sans does.
