The best non-technical introduction I've seen for UTF-8 is "The Properties and Promizes (sic) of UTF-8" by Martin Dürst, here:
http://www.ifi.unizh.ch/mml/mduerst/papers/PDF/IUC11-UTF-8.pdf And another good easy introduction is Richard Gillam's "Unicode Demystified", here: http://www.concentric.net/~rtgillam/pubs/unibook/ Look into chapter 6, "Encoding Forms", which has useful illustrations of the UTFs. _________________________________________________________________ Join the world’s largest e-mail service with MSN Hotmail. http://www.hotmail.com
