-=item \p{} uses Unicode rules, not locale rules
-
-(W) You compiled a regular expression that contained a Unicode property
-match (C<\p> or C<\P>), but the regular expression is also being told to
-use the run-time locale, not Unicode.  Instead, use a POSIX character
-class, which should know about the locale's rules.
-(See L<perlrecharclass/POSIX Character Classes>.)
-
-Even if the run-time locale is ISO 8859-1 (Latin1), which is a subset of
-Unicode, some properties will give results that are not valid for that
-subset.
-
-Here are a couple of examples to help you see what's going on.  If the
-locale is ISO 8859-7, the character at code point 0xD7 is the "GREEK
-CAPITAL LETTER CHI".  But in Unicode that code point means the
-"MULTIPLICATION SIGN" instead, and C<\p> always uses the Unicode
-meaning.  That means that C<\p{Alpha}> won't match, but C<[[:alpha:]]>
-should.  Only in the Latin1 locale are all the characters in the same
-positions as they are in Unicode.  But, even here, some properties give
-incorrect results.  An example is C<\p{Changes_When_Uppercased}> which
-is true for "LATIN SMALL LETTER Y WITH DIAERESIS", but since the upper
-case of that character is not in Latin1, in that locale it doesn't
-change when upper cased.
