=item ${^ENCODING}
X<${^ENCODING}>

This variable is no longer supported.

It used to hold the I<object reference> to the C<Encode> object that was
used to convert the source code to Unicode.

Its purpose was to allow your non-ASCII Perl
scripts not to have to be written in UTF-8; this was
useful before editors that worked on UTF-8 encoded text were common, but
that was long ago.  It caused problems, such as affecting the operation
of other modules that weren't expecting it, causing general mayhem.

If you need something like this functionality, it is recommended that use
you a simple source filter, such as L<Filter::Encoding>.

If you are coming here because code of yours is being adversely affected
by someone's use of this variable, you can usually work around it by
doing this:

 local ${^ENCODING};

near the beginning of the functions that are getting broken.  This
undefines the variable during the scope of execution of the including
function.

This variable was added in Perl 5.8.2 and removed in 5.26.0.
