9.7.3.2. Bracket Expressions says "Standard character class names are:
alnum, alpha, blank, cntrl, digit, graph, lower, print, punct, space, upper,
xdigit". The class "ascii" exists, but is not mentioned (probably a
combination of some of the other classes). Are there any other classes? Do
they work only for ASCII characters (e.g. '\u00A0' is not picked up by
'[:blank:]')?
