latex2html -html_version 3.2,latin2 .... myfile.docdeclares that any 8-bit characters in the LATEX source within the file myfile.doc are to be interpreted according to the ISO-8859-2 (ISO-Latin2) font encoding, rather than the default of ISO-8859-1 (ISO-Latin1).
Furthermore, ISO-10646 (Unicode) entities can be embedded within the output produced by LATEX2HTML. For this a further ``extension'' option is appended; viz.
latex2html -html_version 3.2,latin2,unicode .... myfile.docdeclares that the input is ISO-Latin2, but that 8-bit characters be output as the corresponding Unicode number. For example, e.g. the Polish would become Ł. Otherwise the browser might render the character as , which is the character in the corresponding place for ISO-Latin1. The input encodings that are recognised are listed in the following table.
If multiple extension options are requested, then later ones
override earlier ones.
Only in rare circumstances should it be necessary to do this. For example, if the latter encoding does not define characters in certain places, but an earlier encoding does so, and these characters occur within the source. In this case the unicode extension ought to be loaded also, else browsers may get quite confused about what to render.
