How does gtk display glyph with code in private use area?

[Ferdinand Ramirez <ramirez ferdinand yahoo com>]

I added a glyph using fontforge to a ttf file. The glyph is in private use area and has the code 010005. How 
do I display this using gtk? However, my program does not display the glyph.

If I add the glyph with unicode value with something like 46DB or a value which is not in the private use 
area, I am able to display it using gtk function g_locale_to_utf8 and then inserting it into the text buffer. 
I need to be able to do the same thing with code values in the private use area.

Also, what if I add a glyph in a plane that is unassigned but not in the private use area? Will I have to 
have any special code to deal with that situation?
