 Hello,

 I recently noticed an issue with non-breaking spaces: when inserted with
 keyboard shortcuts (like `ALT+255` on Windows or `ALTGr+<` using an
 enhanced keyboard), they seem to be removed by WordPress (or not
 interpreted as such at all).

 We need to add them either by typing ` ` or by pasting it from an
 external file. Which is not very convenient.

 With @webaxones and @audrasjb we did some digging, here's what we found:

 1/ It seems to appear only on Windows (tested on Windows 10) since JB
 tested it on his Mac and couldn't reproduce it

 2/ It does not seem to be browser specific since we reproduced the bug on
 Chrome 78.0.3904.70 and Firefox 70.0;

 3/ It's not plugin related since I've been able to reproduce it on a fresh
 install;

 4/ It's not somehow Gutenberg related since I've been able to reproduce it
 on a totally random old version: WP 4.7.7 (fresh install as well, haven't
 tried with older versions);

 5/ It may be related to #26842;

 6/ Other shortcuts works fine;

 7/ We tested the shortcuts on other browser-based editors (like Google
 Docs) and they work fine.


 As far as we know, it could be either (or both):
 - A very old issue with WordPress
 - A bug related to a change made in Windows or in browsers that affects
 how WordPress interacts with these shortcuts.

 Thanks,
