Comment:

 Replying to [comment:2 RavanH]:
 > Strange, I tested on several other installations and on some the single
 quote gets converted to `’` (invalid) but on others to `’`
 (valid).

 `’` is a [source:tags/5.2.1/src/wp-
 includes/formatting.php?marks=102,103#L101 translatable string] in
 `wptexturize()`, so some locales may have translated it to `’`.

 For feeds, we generally run the content through
 [https://developer.wordpress.org/reference/functions/ent2ncr/ ent2ncr] and
 [source:tags/5.2.1/src/wp-includes/default-filters.php?marks=214-229#L213
 other filters] to prevent this kind of issues. Looks like in addition to
 post titles we have to run it on term titles as well.
