Insert a shape as a glyph

Hi,
I have to adapt my application to different languages, and the globalization library offers an excellent service in converting currencies etc, but I have a problem: I need to localize my app for Turkey too, and I need to show the Turkish Lira symbol, a glyph that is so recent that it has not been inserted in all the OS’ unicodes yet.
How can I bypass this problem? Can I add a shape as a new glyph to a font?

Do you know tricks for this kind of problems?
Thanks
