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. >From a typographic point of view, I figured url links in footnotes are not that unusual.
