Ok, and The MS PRGothic font is different than Mona.
Differences: Letters in the Mona font is slightly tallers and a few symbols disappear at bigger sizes. The MS PRGothic font is the same size as the MS PGothic font, and the symbols don't disappear when viewed at bigger sizes.
By the way, You should add the MS PGothic font for Linux users if they have the MS Gothic and MS Mincho font collection installed in their /.fonts/ folder.
