=item *

Printable Unicode characters appear as themselves instead of \x{ABCD}.

Note: If your data contains 'wide characters', you should
C<< use open IO => ':locale'; >> or otherwise arrange to
encode the output for your terminal.
You'll also want C<< use utf8; >> if your Perl source
contains characters outside the ASCII range.

Undecoded binary octets (e.g. data read from a 'binmode' file)
will still be escaped as individual bytes.

Depending on options, spaces·may·be·shown·visibly
and '␤' may be shown for newline (and similarly for other ASCII controls).

"White space" characters in qr/compiled regex/ are shown as \t, \n etc.
