ANYOFPOSIXL ANYOF, sv charclass_posixl S ; Like ANYOFL, but matches [[:posix:]] classes
-ANYOFH ANYOF, sv 1 S ; Like ANYOF, but only has "High" matches, none in the bitmap; non-zero flags "f" means "f" is the first UTF-8 byte shared in common by all code points matched

+ANYOFHb ANYOF, sv 1 S ; Like ANYOFH, but all matches share the same first byte, the repurposed flags field contains it
ANYOFM ANYOFM byte 1 S ; Like ANYOF, but matches an invariant byte as determined by the mask and arg
NANYOFM ANYOFM byte 1 S ; complement of ANYOFM
