I don't think that's within the scope of this patch. "UTF-8" is not
a valid locale setting on Linux and so Python should not allow
passing this through the locale normalization process on Linux.

Please also note that SSH does not forward arbitrary env vars.
Only a select few are forwarded and all others have to be
configured. The locale vars are not among the default ones
(see the ssh man page for details).

Aisde: While looking into this I found that the locale module
aliases C.UTF-8 to en_US.UTF-8. This was added as part of
issue #20076 and originates from the X.org locale.alias file.
Time machine and all that :-)
