There's nothing here that implies a bug in bash. Try running "locale" in your 
remote shell. The meaning of the variables printed by that command is defined 
by https://pubs.opengroup.org/onlinepubs/9699919799/basedefs/V1_chap07.html. 
Should the effective value of LC_MESSAGES not be to your liking, you are free 
to change it, be it in your operating system, in your login shell environment 
or in your scripts. Incidentally, by default, the sshd_config(5) shipped by 
macOS defines "AcceptEnv LANG LC_*", meaning that it honours all of the 
environment variables pertaining to the locale, as conveyed by the ssh(1) 
client.
