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
classification of just the first (possibly multi-byte) 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> is like the C<isFOO_A> and C<isFOO_L1> variants, but the
+result is based on the current locale, which is what C<LC> in the name stands
+for. If Perl can determine that the current locale is a UTF-8 locale, it uses
+the published Unicode rules; otherwise, it uses the C library function that
+gives the named classification. For example, C<isDIGIT_LC()> when not in a
+UTF-8 locale returns the result of calling C<isdigit()>. FALSE is always
+returned if the input won't fit into an octet. On some platforms where the C
+library function is known to be defective, Perl changes its result to follow
+the POSIX standard's rules.
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
