One of the siggraph papers is titled ‘FontCode: Embedding Information in Text Documents using Glyph Perturbation’. This is a type of steganography where the shape of the font is perturbed in a way to encode information. Basically, you make a key value store (a code book in their jargon) of input letters mapped to subtle variations of the same letter of a specific font. My confusion arises from how you get Microsoft word to use these variations. Since the font file on your pc contains only one glyph for each letter, how do you get a text editor to use bastardized glyphs that are not in the OS?
