Embedded fonts and non-latin characters not showing

With the font I have embedded any non-latin characters dont show.
How should I handle this ?
If I install the font to windows and load the font without embedding it behaves nicely and shows asian/russian etc characters along with the latin ones. is it possible to do this on iOS and Android ?
Thanks

Is this the Flash target, or on the desktop targets?

It could be a unicode issue, not a font issue.

I believe we include all of the glyphs from the font, not just Latin ones
