My aim is simple: I want to add custom glyphs to the font file with custom codes assigned to these glyphs and display these glyphs in gtktextview when I press a key to which I map to the code.

And I want to achieve this programatically and not by other means such as figuring out commands to replace maps.

I have successfully managed to do all the above by assigning an unused unicode value but not a value in the private user area. At some point, I even want to try out codes that are 64 bits long.

Trust me, I probably will learn something new from you! So thanks for responding.

I did not mean a different glyph every time, but that I want to choose a value for the code outside the range specified by the unicode standards. For example, if I have a 64 bit architecture, can I choose a code value wider than 32 bits and still expect gtk to work if the font file has this code mapped to the glyph?

I just meant that I am looking for a programmatic solution and not commands to replace maps behind the scene.

I use gtk on linux and I add glyphs to existing ttf font files using fontforge.
