Change 14505 by jhi@alpha on 2002/01/31 15:26:41
Turn the I/O Unicode error by default on, but the
character-generating Unicode error by default off,
as Larry suggested.

+one. This warning is by default on for I/O (like print) but can be
+turned off by C<no warnings 'utf8';>. You are supposed to explicitly
