OTOH, the probability that the visitor has a PDF reader is much higher.
Plus the PDF is usually much easier to index etc. But yes, using this to
build a website is PITA.

You could as well run htmltidy or something like that on the HTML. But
in both cases, this will seriously damage the formatting. So if the OP
wants to preserve it, the only viable solution is to keep the .doc
format or convert it to a .pdf and pray there's a working viewer.
Or you can convert the PDF into images ("convert" from imagemagick can
do that quite easily), display those images on the web and offer the PDF
for download.
