In this case, you have to C<use charnames> to load the Unicode names of the
characters, otherwise Perl will complain.
-To specify by Unicode ordinal number, use the form
+To specify a character by Unicode code point, use the form
C<\N{U+I<wide hex character>}>, where I<wide hex character> is a number in
hexadecimal that gives the ordinal number that Unicode has assigned to the
desired character. It is customary (but not required) to use leading zeros to
pad the number to 4 digits. Thus C<\N{U+0041}> means
-C<Latin Capital Letter A>, and you will rarely see it written without the two
+C<LATIN CAPITAL LETTER A>, and you will rarely see it written without the two
leading zeros. C<\N{U+0041}> means "A" even on EBCDIC machines (where the
ordinal value of "A" is not 0x41).
