C<isWORDCHAR_uvchr(0x100)> returns TRUE, since 0x100 is LATIN CAPITAL LETTER A
WITH MACRON in Unicode, and is a word character.
-Variant C<isI<FOO>_utf8_safe> is like C<isI<FOO>_uvchr>, but is used for UTF-8
-encoded strings. Each call classifies the first character of the string. 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

-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 v5.32, 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
-extra measure of protection, or you can wait until v5.32, when you'll be forced
-to add the C<e> parameter.
