I am taking night classes in Chinese at my local high school and want to buy a ruby font (pinyin and hanzi) to use for my homework essays. I'm looking for recommendations.

Ideally, the font should include both traditional and simplified characters
and should be installable on both Mac OS X 10.5 and Windows XP or later.

I read the comments on Chinese Mac:

They indicate that DynaLabs sells such fonts but I don't see any in the store.

Would you please recommed a ruby font that would meet my needs?

Thank you in advance for your input.
