Name of contribution: ucharclasses Version number: 1.0 Author's name: Michiel Kamermans Location on CTAN: /macros/xetex/latex/ucharclasses Summary description: A XeLaTeX package for automatic code insertion between unicode blocks, such as automatic font switching for different languages License type: other-nonfree
Announcement text: ---------------------------------------------------------------------- This package addresses one of the few features where TeX still has to play catch-up to word processing programs: automatic font switching for different languages. In fact, it goes one better than word processing programs and comes with macros for inserting arbitrary code between text from different unicode blocks, by making use of XeTeX's little known intercharclass behaviour.
