Almost correct: C2 not C0. And with perl-5.16, you don't even need to load charnames ☺

% bleadperl -C2 -E'say"\N{FACE WITH TEARS OF JOY}"'

I did not suggest -C0, I said -CO, as in capital o, not the number 0. From man perlrun:

  As of 5.8.1, the "-C" can be followed either by a number or a list
  of option letters.  The letters, their numeric values, and effects
  are as follows; listing the letters is equal to summing the
  numbers.

    I     1   STDIN is assumed to be in UTF-8
    O     2   STDOUT will be in UTF-8
    E     4   STDERR will be in UTF-8
    S     7   I + O + E
    i     8   UTF-8 is the default PerlIO layer for input streams
    o    16   UTF-8 is the default PerlIO layer for output streams
    D    24   i + o
    A    32   the @ARGV elements are expected to be strings encoded
              in UTF-8
    L    64   normally the "IOEioA" are unconditional,
              the L makes them conditional on the locale environment
              variables (the LC_ALL, LC_TYPE, and LANG, in the order
              of decreasing precedence) -- if the variables indicate
              UTF-8, then the selected "IOEioA" are in effect

Mea culpa. /me is too used to using digits I didn't see.


Enjoy, Have FUN! H.Merijn
