Variant C<isFOO_L1> imposes the Latin-1 (or EBCDIC equivlalent) character set
onto the platform. That is, the code points that are ASCII are unaffected,
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).

+Variant C<isFOO_uvchr> is like the C<isFOO_L1> variant, but accepts any UV code

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