Why when I run this one-liner:

perl -e 'print "\x{2660}\n"'

do I see this:

Wide character in print at -e line 1.

I'm assuming that's a warning, since I still get the expected output, but why am I getting it, when I didn't ask for them?

Is there a better way to drop in a unicode character?

Semi-related question: Is there a good document I could read somewhere on the differences for one-liners in Windows?

Thanks.

James
