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.
Best Regards,
Michael
