I don't know Encode well enough to check if there are any other places
this
will strike.
I think we'd better leave that way; It needs a PV to (en|de)code so
consider this a feature.
I agree that passing undef() to one of the encoding functions may be an edge
condition too far, but passing a variable that contains undef is more
common.
$ perl5.7.3 -w -MEncode -e 'Encode::encode_utf8($a)'
Name "main::a" used only once: possible typo at -e line 1.

Can this be detected & silenced?
Of course
perl5.7.3 -w -MEncode -e 'Encode::encode_utf8("")'
is perfectly safe and legal.
