in reply to Uncommon* but Useful Perl Command Line Options for One-liners

As I alluded to, with 5.8.1,
-C              enable native wide character system interfaces
-C[number/list] enables the listed Unicode features
and it would be better, IMO, to show the newer --help. From the perldelta for 5.8.1:
The -C Switch Has Been Repurposed

The -C switch has changed in an incompatible way. The old semantics of this switch only made sense in Win32 and only in the "use utf8" universe in 5.6.x releases, and do not make sense for the Unicode implementation in 5.8.0. Since this switch could not have been used by anyone, it has been repurposed. The behavior that this switch enabled in 5.6.x releases may be supported in a transparent, data-dependent fashion in a future release.

For the new life of this switch, see perl581delta "UTF-8 no longer default under UTF-8 locales", and perlrun/-C.
