Firstly you're not passing a parameter to perl's -F. '' is
interpreted by the shell to mean 'the empty string', so what
follows the F is the empty string.
To pass literal quotes to the program (perl) you need to
escape them stick them or stick them in quotes:
bash-2.05a$ perl -aF"''" -ne 'print map{unpack"B8",[EMAIL PROTECTED]'
abc
01100001011000100110001100001010
bash-2.05a$ perl -aF'""' -ne 'print map{unpack"B8",[EMAIL PROTECTED]'
abc
01100001011000100110001100001010
bash-2.05a$ perl -aF\"\" -ne 'print map{unpack"B8",[EMAIL PROTECTED]'
abc
01100001011000100110001100001010
bash-2.05a$ perl -aF\'\' -ne 'print map{unpack"B8",[EMAIL PROTECTED]'
abc
01100001011000100110001100001010
However, you also have the option of achieving the same effect
without using quoe characters to bound the -F regexp, so none
of the above are desirable for perl golfing.
