[l2h] Converting emdashs and endashs?

[Arthur Snoke]

Part of what is going on, I think, is that Microsoft and Netscape have
chosen to use different values for things like dashes and quotes.  I am
told there is a range of values which were not to be used, but those guys
chose to anyway.  So an em-dash is —, etc.  All browsers recognize
these, but when one tries to do validation tests on a page using
<http://validator.w3.org/>, it will tell you that such character encodings
are not "correct."  Not all browsers recognize the "official" &#8212; for
the em-dash.
