If you can elaborate on the technical problem I can give it a look.
If the glyph is limited to one character and is properly cached I don't
see why this would be a specificaly worrisome performance hit. I can
see it being an issue if the glyph is changed a lot, but I don't think
this is a common use case.
I'm making some assumptions about the display code, I'll take a look at
the implementation.
