 The special value 00 will cause Perl to slurp files in paragraph mode.

+Any value 0400 or above will cause Perl to slurp files whole, but by convention

-If you want to specify any Unicode character, use the hexadecimal

+You can also specify the separator character using hexadecimal notation:
+C<-0xHHH...>, where the C<H> are valid hexadecimal digits.  Unlike the octal
+form, this one may be used to specify any Unicode character, even those beyond
+0xFF.
 (This means that you cannot use the C<-x> with a directory name that
 consists of hexadecimal digits.)
