Alan Wood's Unicode Resources
A wealth of information about Unicode on various platforms and browsers. Constantly updated and highly recommended, even if not all parts of this site has been updated. Includes e.g. list of fonts sorted by the languages that they can be used for, advice on web browsers etc.
This project headed by Johannes Bergerhausen, Mainz, will collect information about all characters in the Unicode Standard. The aim of this wikipedia-style project is to create a basis for fundamental typographic research and to facilitate a textual approach to the characters of the world for all computer users. Well worth a visit.
