Comment (by leonardo.schenkel@…):

 This is what I suspected, but I just wanted to confirm before blaming your
 set-up.

 Unfortunately the LC_CTYPE="UTF-8" that Terminal.app sets by default is
 not a valid recognized locale by a lot of software (the locale is supposed
 to be something like "de_CH.UTF-8"). The macOS userland can cope with it
 (and many BSD as well), but if you ever ssh to a Linux box for example
 you'll instantly get this warning: `setlocale: LC_CTYPE: cannot change
 locale (UTF-8)` because the value is rejected by the GNU userland.

 Mutt 1.7 is now being affected by this. Before 1.7 it didn't pay attention
 to your environment's locale (only to the locale you set in the
 configuration file), but that setting was removed and it is now determing
 the locale and the charset based on the environment variables, like
 virtually all other software does. Unfortunately it got bitten by the
 broken macOS defaults.

 This is so annoying in general that on my shell initialization scripts I
 have the following:
 {{{
 if [ "${LC_CTYPE}" == "UTF-8" ]; then
   # OS X likes to set LC_CTYPE="UTF-8". In general this is supported by
 BSD
   # systems, but not Linux (which will become a problem when ssh'ing to
   # foreign systems). Check if it is possible to unset LC_CTYPE without
   # changing the charset, and unset it if that is true.
   if [ "$(LC_CTYPE= locale charmap)" == "UTF-8" ]; then
     unset -v LC_CTYPE
   fi
 fi
 }}}

 If you change your shell initialization scripts to contain `export
 LANG=de_CH.UTF-8` (or whatever is your locale of choice) *before* the
 snippet above, then LC_CTYPE will be automatically unset and you should
 not have any more of these issues.

 Note that as "cal" have correctly said, the change of behavior that you
 have experienced was introduced vanilla Mutt, not NeoMutt neither this
 port. All I can do in this situation is to suggest you to change your
 settings.
