What if you first converted your rendered text to a graphic via the ImageMagik
libraries for iOS?

I'm not familair with MonoTouch Text rendering, but I found some
StackOverflow posts that seem to indicate that CGContext has no
support for anything other than ASCII/MacRoman text, and that you
should use CoreText or UIView.DrawString:

http://stackoverflow.com/questions/1564577/converting-a-nsstring-to-a-cstring-for-use-with-cgcontextshowtextatpoint
http://stackoverflow.com/questions/7672453/custom-font-does-not-render-correctly-when-using-showtext
http://stackoverflow.com/questions/275437/unicode-character-not-showing
I've cc'd the message to the MonoTouch list, maybe someone there can
help with this.
