+(F)
+C<\N> has two meanings.
+
+The traditional one has it followed by a name enclosed
+in braces, meaning the character (or sequence of characters) given by that name.
+Thus C<\N{ASTERISK}> is another way of writing C<*>, valid in both
+double-quoted strings and regular expression patterns. In patterns, it doesn't
+have the meaning an unescaped C<*> does.
+
+Starting in Perl 5.12.0, C<\N> also can have an additional meaning (only) in
+patterns, namely to match a non-newline character. (This is short for
+C<[^\n]>, and like C<.> but is not affected by the C regex modifier.)
+
+This can lead to some ambiguities. When C<\N> is not followed immediately by a
+left brace, Perl assumes the C<[^\n]> meaning. Also, if
+the braces form a valid quantifier such as C<\N{3}> or C<\N{5,}>, Perl assumes
+that this means to match the given quantity of non-newlines (in these examples,
+3; and 5 or more, respectively). In all other case, where there is a C<\N{>
+and a matching C<}>, Perl assumes that a character name is desired.
+
+However, if there is no matching C<}>, Perl doesn't know if it was mistakenly
+omitted, or if C<[^\n]{> was desired, and
+raises this error. If you meant the former, add the right brace; if you meant
+the latter, escape the brace with a backslash, like so: C<\N\{>
