Fontes intelligentes, textèmes et typographie dynamique

The digital text representation model used by the industry today is the model proposed by the Unicode standard. This model, based on the concepts of character and glyph, provides the foundations for the so-called smart font technologies such as AAT, OpenType and Graphite. Using a formal description of Unicode's text model, the authors compare the three said font formats, especially regarding paragraph breaking and how mapping information is preserved between characters and glyphs, in other words, between content and presentation. In the second part of the paper, the authors propose a novel approach to these two problems through an alternative text model based on the texteme concept and dynamic typography.
