Hi all.

Modify your LaTeX preamble as follows:
%&latex
\documentclass{article}
\usepackage{html}
%begin{latexonly}
\renewcommand{\htmladdnormallinkfoot}[2]{#1{\footnote{\htmlurl{#2}}}}
%end{latexonly}
\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}
The 1st and 3rd examples now work in PDF, and moreover have become
active links there.
The 2nd example doesn't work however.
But that can be fixed too, by also including a redefinition of \~
that tests whether the argument is empty or not.
For example, using the following works for all 3 above examples...
%begin{latexonly}
\newcommand{\testtilde}[1]{%
\ifx\relax#1\relax\noexpand~\else\noexpand\~#1\fi}
%
\renewcommand{\htmladdnormallinkfoot}[2]{#1{\bgroup
\def~{\noexpand~}\let\~\testtilde
\edef\next{\egroup \def\noexpand\thisurl{#2}}\next
\expandafter\footnote\expandafter{\expandafter\htmlurl\expandafter
{\thisurl}}}}
%end{latexonly}
... but there are no guarantees of what it does when the URL
argument (that is, the #2) has active characters other than ~ .
Hope this helps,
Ross
