Unicode is not a markup language like HTML, but an expanded "universal"
character set.

The ASCII character set uses 7 bits per character and can encode a total of
128 characters (the upper and lower-case alphabets, numbers, basic
punctuation, and control characters). Since ASCII lacks a lot of characters
people want to use (such as accented vowels), ASCII has been extended to 8
bits (256 characters) - there are several 256-character standards. Unicode
is a further, much broader extension, to 16 bits (65,536 characters) -
enough so that you can write most human languages in Unicode characters.
Unicode includes, among much else, the m-dash that started this thread a
few days ago.

There is some relationship between HTML and Unicode: HTML 3.2, by default,
used ISO-Latin, the most widespread of the 256-character standards. HTML
4.0 uses Unicode. Since ISO-Latin is a subset of Unicode - the first 256
characters of Unicode are the same as the 256 characters in ISO-Latin -
there is backward compatibility from Unicode to the older standard.
Unfortunately, the browser makers are still working on forward
compatibility. ;-)
