Ok, using org-element, we could escape special symbols - for now, only '#', '%' and '&' come to mind - in http links iff they are inside a footnote and exporter backend is latex. As I said, if this is too special a case to be supported, I was playing around with regexps and `org-export-filter-final-output-functions' as seen e.g. in [1]. On other occasions that involved in-buffer replacements, I had success using group matching with the `re-search-forward', `replace-match' and `match-string' functions (see also [2]). But IIUC, since the export filter function gets passed a string with the .tex export results, I need a function that operates on a string such as `replace-regexp-in-string' as seen in [1]. Now I assume for in-string regexp replacement and the use case at hand I would need a (missing) lookbehind feature [3], don't I? Please let me know whether you think this is feasible.
