"""
``char_index`` builds an inverted index mapping words to sets of Unicode
characters which contain that word in their names. For example::

    >>> index = char_index(32, 65)
    >>> sorted(index['SIGN'])
    ['#', '$', '%', '+', '<', '=', '>']
    >>> sorted(index['DIGIT'])
    ['0', '1', '2', '3', '4', '5', '6', '7', '8', '9']
    >>> index['DIGIT'] & index['EIGHT']
