Comment (by RavanH):

 After 10 years, this bug seems to be back in 5.2.1

 On a completely fresh install (no plugins, default theme) I added a tag
 with a ' (single quote) in the title. This converts to `’` in the
 feed title tag. This in turn, generates
 {{{
 This feed does not validate.

 line 11, column 9: XML parsing error: <unknown>:11:9: undefined entity
 }}}
 for the tag feed on https://validator.w3.org/feed/
