=head1 Character classes
-There are three variants for all the functions in this section. The base ones
-operate using the character set of the platform Perl is running on. The ones
-with an C<_A> suffix operate on the ASCII character set, and the ones with an
-C<_L1> suffix operate on the full Latin1 character set. All are unaffected by
-locale.
-
-For ASCII platforms, the base function with no suffix and the one with the
-C<_A> suffix are identical. The function with the C<_L1> suffix imposes the
-Latin-1 character set onto the platform. That is, the code points that are
-ASCII are unaffected, since ASCII is a subset of Latin-1. But the non-ASCII
-code points are treated as if they are Latin-1 characters. For example,
-C<isSPACE_L1()> will return true when called with the code point 0xA0, which is
-the Latin-1 NO-BREAK SPACE.
-
-For EBCDIC platforms, the base function with no suffix and the one with the
-C<_L1> suffix should be identical, since, as of this writing, the EBCDIC code
-pages that Perl knows about all are equivalent to Latin-1. The function that
-ends in an C<_A> suffix will not return true unless the specified character also
-has an ASCII equivalent.
+This section is about functions (really macros) that classify characters
+into types, such as punctuation versus alphabetic, etc. Most of these are
+analogous to regular expression character classes. (See
+L<perlrecharclass/POSIX Character Classes>.) There are several variants for
+each class. (Not all macros have all variants; each item below lists the
+ones valid for it.) None are affected by C<use bytes>, and only the ones
+with C<LC> in the name are affected by the current locale.
+
+The base function, e.g., C<isALPHA()>, takes an octet (either a C<char> or a
+C<U8>) as input and returns a boolean as to whether or not the character
+represented by that octet is in the named class based on platform, Unicode, and
+Perl rules. If the input is a number that doesn't fit in an octet, FALSE is
+always returned.
+
+Variant C<isFOO_A> (e.g., C<isALPHA_A()>) will return TRUE only if the input is
+also in the ASCII character set. For ASCII platforms, the base function with
+no suffix and the one with the C<_A> suffix are identical. On EBCDIC
+platforms, the C<_A> suffix function will not return true unless the specified
+character also has an ASCII equivalent.
+
+Variant C<isFOO_L1> operates on the full Latin1 character set. For EBCDIC
+platforms, the base function with no suffix and the one with the C<_L1> suffix
+are identical. For ASCII platforms, the C<_L1> suffix imposes the Latin-1
+character set onto the platform. That is, the code points that are ASCII are
+unaffected, since ASCII is a subset of Latin-1. But the non-ASCII code points
+are treated as if they are Latin-1 characters. For example, C<isSPACE_L1()>
+will return true when called with the code point 0xA0, which is the Latin-1
+NO-BREAK SPACE.
+
+Variant C<isFOO_uni> is like the C<isFOO_L1> variant, but accepts any UV code
+point as input. If the code point is larger than 255, Unicode rules are used
+to determine if it is in the character class. For example,
+C<isWORDCHAR(0x100)> returns TRUE, since 0x100 is LATIN CAPITAL LETTER A WITH
+MACRON in Unicode, and is a word character.
+
+Variant C<isFOO_utf8> is like C<isFOO_uni>, but the input is a pointer to a
+(known to be well-formed) UTF-8 encoded string (C<U8*> or C<char*>). The
+classification of just the first character in the string is tested.
+
+Variant C<isFOO_LC> is like the C<isFOO_A> and C<isFOO_L1> variants, but uses
+the C library function that gives the named classification instead of
+hard-coded rules. For example, C<isDIGIT_LC()> returns the result of calling
+C<isdigit()>. This means that the result is based on the current locale, which
+is what C<LC> in the name stands for. FALSE is always returned if the input
+won't fit into an octet.
+
+Variant C<isFOO_LC_uvchr> is like C<isFOO_LC>, but is defined on any UV. It
+returns the same as C<isFOO_LC> for input code points less than 256, and
+returns the hard-coded, not-affected-by-locale, Unicode results for larger ones.
+
+Variant C<isFOO_LC_utf8> is like C<isFOO_LC_uvchr>, but the input is a pointer to a
+(known to be well-formed) UTF-8 encoded string (C<U8*> or C<char*>). The
+classification of just the first character in the string is tested.
