A good start is http://www.stonehand.com/unicode.html.
Unicode Version 1.1 and ISO 10646-1993 are identical in many
points; especially, they is full code-point identity. Information
through Unicode is generally a lot cheaper than thourgh ISO.
For specific questions (not related to HTML and what we
are discussing here), refer to the newsgroup comp.std.internat.
