Asian Character issue

Hey all,
I am having a bit of a dilemma right now with some chinese - simplified input boxes.

Here is the set up:
I have a text box that is being generated.
it is using _sans as its font
embedFonts is set to false

now the issue:
when i set my keyboard to Chinese (PRC) / Chinese (Simplified), I am able to start typing and have the proper dialog box come up to create the character, but when i finish the character it disappears.  

I am able to paste text into the box no problem, or set the text value with code, but i cannot seem to manually enter the character.

thanks,
marc
