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.
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?
