Not strange per se, and normal for millions, but do non Roman fonts work in PJ?
Yes!

If you would like to test it, heres a link to four fonts (Chinese, Russian, Hindi and Arabic) – http://1drv.ms/1KoiKC9 and heres a language character generator: http://generator.lorem-ipsum.info/
The filesize of cyrillic fonts are usually larger than roman fonts, probably due to there being more chars. However chinese fonts can be much larger >16mb. Apparently some chinese fonts list 20,000 – 200,000 chars (imagine that keyboard!).
