I had a quick look at the code, but I am similarly stymied at the
moment.  Could the problem be something to with the fact that the
different latex commands used for urls have different requirements for
characters: \href allows #, ~ according to the hyperref documentation,
and it appears, by my own trial and error, to allow $ unescaped as well.
\url, on the other hand is like verbatim: anything except a } is
permissible.

The \footnote commands after the \href commands in each url link type
would, of course, require the same special character handling as normal
text [i.e., different from the \href command].  

\ref and \label take any alphanumeric character and also only -_+=.:;,

Mind you I am not sure how relevant this all is: I haven't any
experience of using images in muse so far [nor urls for that matter].  I
don't actually understand what the different kinds of image are [what is
an embedded image, and what is a non-embedded one?], and I am not quite
clear on the relationship between images and urls.
