`/`` (backtick) gets transformed from MarkDown to <code>96</code> in HTML (and breaks the Atom feed)

[x] I have read the Filing Issues and subsequent “How to Get Help” sections of the documentation.
[x] I can reproduce this problem with stock/default settings file, theme, and sample content (as described in above “How to Get Help” sections of the documentation).
[x] I have searched the issues (including closed ones) and believe that this is not a duplicate.
OS version and name: Linux 5.10.0.29, YunoHost 11.2.30.2 (Debian 11)
Python version: 3.9.2

TL;DR:

suddenly

`\``

gets translated to

<code>96</code>

instead of (as before):

<code>`</code>

and causes issues.

Since I updated Pelican recently, I started running into this issue, so I suspect it is a regression of either Pelican itself or the Python Markdown module.

Suddenly this blog post of mine from 2014 started causing causing issues – specifically the 4^th footnote in it: https://matija.suklje.name/delete-a-sentence-in-vim#fn:q

What happens is that the following Markdown (added linebreak for easier reading):

[^q]: `di"` to delete the text inside quotation marks; and `da"` to delete outside the quotation mark
(to remove surrounding quotations marks as well). Also works with `'` and `\``.

gets translated to HTML as (added linebreaks for easier reading):

<p><code>di"</code> to delete the text inside quotation marks; and <code>da"</code> to delete outside the quotation mark
 (to remove surrounding quotations marks as well). Also works with <code>'</code> and <code>96</code>.&#160;<a
 class="footnote-backref" href="[#fnref:q](view-source:https://matija.suklje.name/delete-a-sentence-in-vim#fnref:q)" 
title="Jump back to footnote 4 in the text">&#8617;</a></p>

As an additional consequence (and this is how I found out through a subscriber) the Atom feed gets broken, see the following two as the broken ones:

Hi,

It’s weird it worked before because your example code doesn’t seem to produce an escaped backtick in markdown but three backticks. You can try here on github for instance:

`\``

produces : ```

I believe the correct syntax is:

Also works with `'` and `` ` ``
