Characters, Glyphs and Beyond
Résumé
The distinction between characters and glyphs is a fundamental issue of computing. This talk aims in giving a new definition of these notions. We first review and comment the definitions given in various standards. Then we give and explain our own definitions. We consider that the Unicode character model is lacunary and formulate a proposal for adding supplementary information and obtaining thus "rich Unicode characters." We illustrate our arguments with many examples, taken from various writing systems.
