Good catch Nick.
Instead of completely backing out the "defined $str or return" change, if
you change it to
unless (defined $str) {
warnif('uninitialized', 'Use of Uninitialized value in encode_utf8');
return;
}
that gives us the same warning behaviour as print/tr/etc, but more
importantly it also gives users of the module the ability to silence the
uninitalized warning in the same way they do with print/tr, thus:
use warnings;
...
{
no warnings 'uninitialized';
Encode::encode_utf8($x);
}
