  I see.

  Seems reasonable.

  I believe (at least) an option to do so would be a good idea.  Adding an
optional 'encoding' parameter is likely the best option.  For a test case, =
is

#!/usr/bin/perl -w

use Encode;
print Encode::encode_utf8( "=E0\n" );
sleep 1;
print Encode::encode_utf8( "=E0\n" );
sleep 1;
print Encode::encode_utf8( "=E0\n" );
print Encode::encode_utf8( "=E0\n" );

a good enough test case?
