Only a little. I suspect this will be one of the issues addresed in
HTML 2.1.
Here's a table that summarizes the HTML character set
as I understand it. Note that characters 27, 127-159, 172,
215, and 247 (decimal) still represent outstanding issues:
27: an escape character for ISO2022 escape sequences?
(the multi-lingual document issue again...)
127-159: is there any defined use for these?
172: in the X fonts, it's a "logical not" character.
Is this part of the ISO8859-1 standard?
What's the SGML entity name (&lnot; ?)
215: in X fonts, it's a "times" character...
2247: in X fonts, it's a "divide" character...
There's also the question of whether PRE lines end in CR, LF, CRLF,
or any of the above.
