A set of Unicode characters, for language-specific strings for

A unicode_set is defined by a list of ranges in the Unicode character

2-tuples or a 1-tuple, such as::
_ranges = [

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