 -- Issue #16455: On FreeBSD and Solaris, if the locale is C, the
 -  ASCII/surrogateescape codec is now used, instead of the locale encoding, to
 -  decode the command line arguments. This change fixes inconsistencies with
 -  os.fsencode() and os.fsdecode() because these operating systems announces an
 -  ASCII locale encoding, whereas the ISO-8859-1 encoding is used in practice.
