if i offer Cherokee font in a Unicode platform. where do you put in a theme?

You face a little problem. Dafont does not have a 'non latin' fonts theme. I think though it should be there. Probably best to send a PM to Rodolphe on this issue.

Chungdehtien, the most important thing is not the character support but the "style" of your font, so it will be listed according to how it looks

I am afraid Fred that then the fonts with a non-latin character set can not be found on Dafont unless the language is incorporated in the font name. When I look at the fonts with a Cherokee character set I have, the Plantage Cherokee (a Windows system font I believe) and the Cherokee those should be classified as Basic Serif and the Cherokee Sans and Aboriginal Sans as Basic Sans serif.
Handy if one searches for a font with a Cherokee character set, regardless of the style. And the same goes of course for Arabic, Hebrew, Cyrillic, Japanese, Thai, Chinese and so on.
So I take the liberty to disagree

Of course, for the moment, it's not possible to look for fonts with a specific character set, so that's why I said that fonts were categorized according to their appearance

Then my advice to Chungdehtien is to make sure that the word Cherokee is part of the Font Family Name and the fonts Full name.

will dafont create a non english theme?
