Since we're on the topic of the classic tilde problem, I have not yet
found a solution that works also for PDF links. For years, I have
been using "\~{}" within \htmladdnormallink{}{}, and that has worked
fine for print and HTML, but for PDF links it fails since I started
using, according to latex -v, pdfetex 3.14592-1.21a-2.2 (which came
with Fedora Core 4). I believe this version of pdfetex came with the
recent tetex 3.0 package, and that it incorporates hyperref
functionality. I first generate PostScript which is then converted
to PDF by ps2pdf. (I can't generate PDF directly because of my
PostScript figures.) In the PDF link, "\~{}" comes out as "~%7b%7d",
which doesn't work as a link. Leaving out "{}" results in a working
PDF link, but no '~' is printed in the footnote. To make PDF links
work, I must leave out '{}' in the second argument to
\htmladdnormallinkfoot{}{}, but then the footnote is printed without
a '~', whether it is escaped with '\' or not. Apparently, \url{} is
not allowed in the second argument to \htmladdnormallinkfoot{}{}
because it is a "moving argument".
I notice that in the PostScript file, each link is included verbatim
(escapes and all) in a context that knows it is a link (based on the
associated function names /URI and /Link). My guess is that ps2pdf
(really ps2pdfwr, which uses ghostscript for the conversion) needs
attention regarding link translation.
If there is a workaround in the LaTeX source, please let me know what it is!
Below is my test file in case anyone wants to try something out quickly:
%&latex
\documentclass{article}
\usepackage{html}
\begin{document}
\begin{enumerate}
\item This
\htmladdnormallinkfoot{link}{http://ccrma.stanford.edu/~jos/} uses
tilde as if it would simply work. The link works in PDF and HTML, but
it is printed in PDF with a space in place of tilde.
\item This
\htmladdnormallinkfoot{link}{http://ccrma.stanford.edu/\~{}jos/webpub/}
uses the standard \verb!\~{}! construct. The PDF link fails, though it
prints ok. The HTML link works.
\item This
\htmladdnormallinkfoot{link}{http://ccrma.stanford.edu/\~jos/pubs.html}
uses \verb!\~! only. The PDF link works, but it prints with the
tilde omitted (no space). The HTML link fails (tilde omitted).
\end{enumerate}
\end{document}

Yes, a tilde is a non-breaking space. So, with
\newcommand{\path}[1]{\texttt{#1}}
I can do something like \path{\~{}/foo} and it works just fine.
But, if I use the \path{} from the url.sty file which provides
some line breaking feature (?? I really have to go check why I'm
using this I think ??) then "\" and "{}"s are printed verbatim.
So, I guess I have to use the same macro for both latex and latex2html.
Anyone have a simple solution?
url.sty provides "sensible" breaks that are useful in long urls.
since it postdates the invention of l2h, there's never been an
adequate way of dealing with it in l2h.
if you want to have typeset urls in your documents, i would recommend
having latex-only and html-only sections, load url in a latex-only
section and do "proper" urls in that, and do the old-fashioned
non-breakable \texttt-style urls in the html sections.
otoh, if you don't need anything more complicated than your ~/foo
things, you might as well forget url.sty altogether.

Thanks for this.
I have just taken the easy way out and am using a macroized texttt{}
to print my paths in the document. This now works fine in the l2h
and latex version. Of course, I did have to fix the tildes, but that
was not a big deal.
Interesting is that I have some tildes in urls, like
\url{http://mypage.uniserve.com/~bvdp} and the tilde in this case
prints find in both l2h and latex versions. I'm no tex-expert, but
looking at url.sty I was assuming that \path{} and \url{} were
pretty much the same.
Oh, one other interesting difference is that with the url version of
\path{} I get a larger "~" centered (vertically) on the line; with
\textt{} I get a smaller, raised "~". Why the difference?
I don't have any really long paths so my hack seems to work fine.
But, it would be nice if url.sty worked with both versions. Maybe
when you have absolutely nothing else to do :)
