as if they are Latin-1 characters. For example, C<isWORDCHAR_L1()> will return
true when called with the code point 0xDF, which is a word character in both
ASCII and EBCDIC (though it represents different characters in each).
+If the input is a number that doesn't fit in an octet, FALSE is returned.

-Variant C<isI<FOO>_uvchr> is like the C<isI<FOO>_L1> variant, but accepts any UV code

C<isWORDCHAR_uvchr(0x100)> returns TRUE, since 0x100 is LATIN CAPITAL LETTER A

-Variant C<isI<FOO>_utf8_safe> is like C<isI<FOO>_uvchr>, but is used for UTF-8
-encoded strings. Each call classifies one character, even if the string
-contains many. This variant takes two parameters. The first, C<p>, is a
-pointer to the first byte of the character to be classified. (Recall that it
-may take more than one byte to represent a character in UTF-8 strings.) The
-second parameter, C<e>, points to anywhere in the string beyond the first
-character, up to one byte past the end of the entire string. The suffix
-C<_safe> in the function's name indicates that it will not attempt to read
-beyond S<C<e - 1>>, provided that the constraint S<C<s E<lt> e>> is true (this
-is asserted for in C<-DDEBUGGING> builds). If the UTF-8 for the input
-character is malformed in some way, the program may croak, or the function may
-return FALSE, at the discretion of the implementation, and subject to change in
-future releases.
-
-Variant C<isI<FOO>_utf8> is like C<isI<FOO>_utf8_safe>, but takes just a single
-parameter, C<p>, which has the same meaning as the corresponding parameter does
-in C<isI<FOO>_utf8_safe>. The function therefore can't check if it is reading
-beyond the end of the string. Starting in Perl v5.30, it will take a second
-parameter, becoming a synonym for C<isI<FOO>_utf8_safe>. At that time every
-program that uses it will have to be changed to successfully compile. In the
-meantime, the first runtime call to C<isI<FOO>_utf8> from each call point in the
-program will raise a deprecation warning, enabled by default. You can convert
-your program now to use C<isI<FOO>_utf8_safe>, and avoid the warnings, and get an

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.

+
+Variants C<isI<FOO>_LC_utf8> and C<isI<FOO>_LC_utf8_safe> are like
+C<isI<FOO>_LC_uvchr>, but are used for UTF-8 encoded strings. The two forms
+are different names for the same thing. Each call to one of these classifies
+the first character of the string starting at C<p>. The second parameter,
+C<e>, points to anywhere in the string beyond the first character, up to one
+byte past the end of the entire string. Although both variants are identical,
+the suffix C<_safe> in one name emphasizes that it will not attempt to read
beyond S<C<e - 1>>, provided that the constraint S<C<s E<lt> e>> is true (this
is asserted for in C<-DDEBUGGING> builds). If the UTF-8 for the input
character is malformed in some way, the program may croak, or the function may
return FALSE, at the discretion of the implementation, and subject to change in
future releases.
-Variant C<isI<FOO>_LC_utf8> is like C<isI<FOO>_LC_utf8_safe>, but takes just a single
-parameter, C<p>, which has the same meaning as the corresponding parameter does
-in C<isI<FOO>_LC_utf8_safe>. The function therefore can't check if it is reading
-beyond the end of the string. Starting in Perl v5.30, it will take a second
-parameter, becoming a synonym for C<isI<FOO>_LC_utf8_safe>. At that time every
-program that uses it will have to be changed to successfully compile. In the
-meantime, the first runtime call to C<isI<FOO>_LC_utf8> from each call point in
-the program will raise a deprecation warning, enabled by default. You can
-convert your program now to use C<isI<FOO>_LC_utf8_safe>, and avoid the warnings,
-and get an extra measure of protection, or you can wait until v5.30, when
-you'll be forced to add the C<e> parameter.
