I agree that passing undef() to one of the encoding functions may be an

$ perl5.7.3 -w -MEncode -e 'Encode::encode_utf8($a)'
Name "main::a" used only once: possible typo at -e line 1.
Use of uninitialized value in subroutine entry at
/tmp/bleed/lib/perl5/5.7.3/sun4-solaris/Encode.pm line 183.
Can this be detected & silenced?
You've got a point. Warning should warn when and only when there is a
danger therein and passing undef itself is harmless. And this can be
done easily by adding "defined $str or return;" for each sub concerned.
Okay, I'll go for that.
