In that case, you should be using the command-line switches:

 latex2html -html_version 4.0,latin1,unicode,utf8,.....
                                     ^^^^^^^^^^^^

or have the $HTML_OPTIONS variable set to include these.

While you are thinking about this topic, please test this.
These extensions have been available for a long time now,
but I've not seen many examples of web-pages using them.

It would be nice to think that most of your audience is keeping up.
Hopefully that is true, at least in the more affluent countries.

With the 'latin1,unicode'  options as above
 (actually the 'latin1' should be redundant)
then LaTeX2HTML should catch the \H{o} and replace it by ő

With also 'utf8' (or $USE_UTF8 = 1; )
then this ő should be replace by a 2-byte sequence, later in
the processing.


If you cannot get this to work, then report back to me with an example
(and a URL to the bad results).


Hope this helps,
