Thanks for your answer. `\url` can handle hash symbols in its argument
without escaping alright - as can be expected. AFAICS, the problem lies
in the `\footnote` command. And yes, I was thinking of `ox-latex`
figuring out that the url is in a footnote and escape accordingly.
I can see that the export engine should not and cannot cover all special
cases, but since links and footnotes are `first-class` org-mode
concepts, it would be nice to have them play along in this situation.
