I think you've accidentally looked at the wrong file.... that
is in the ppttohtml.pl script, which converts powerpoint (ppt).

The pdftohtml.pl script has the following:
$cmd .= " -noframes -p -enc UTF-8 "$input_filename" "$output_filestem.htm'"";

which should do the right thing. I'm not sure why it gives the warning
message though... perhaps you could email me (personally, not the list)
a copy of a pdf that exhibits this behaviour? pdftohtml.pl definitely
works on non-ascii characters for the documents that we've tested with.
