Typo fix
TAP encoding/UTF8 support

This makes the 'modern' flag in test more switch to utf8 for the
package. You can also use the 'utf8' flag, or encoding => 'utf8'.

This is a lexical-to-package setting. You can also use other encodings.

Packages that use Test::More without setting encoding get set to
'legacy' encoding, which does what Test::More has always done.

Packages with no setting use utf8 if it has already been enabled by
something else, otherwise they use legacy.
