33 A set of Unicode characters, for language-specific strings for
34 ``alphas``, ``nums``, ``alphanums``, and ``printables``.
35 A unicode_set is defined by a list of ranges in the Unicode character
36 set, in a class attribute ``_ranges``. Ranges can be specified using
37 2-tuples or a 1-tuple, such as::
39 _ranges = [
40 (0x0020, 0x007e),
41 (0x00a0, 0x00ff),

45 Ranges are left- and right-inclusive. A 1-tuple of (x,) is treated as (x, x).
47 A unicode set can also be defined using multiple inheritance of other unicode sets::
