+ --------------------------------------------------------------------
+
+ * Yet another Unicode string type for Python. This type supports the
+ * 16-bit Basic Multilingual Plane (BMP) only.
+ *
+ * Note that this string class supports embedded NULL characters. End
+ * of string is given by the length attribute. However, the internal
+ * representation always stores a trailing NULL to make it easier to
+ * use unicode strings with standard APIs.
+ *
+ * History:
+ * 1999-01-23 fl Created
+ * 1999-01-24 fl Added split, join, capwords; basic UTF-8 support
+ * 1999-01-24 fl Basic UCS-2 support, buffer interface, etc.
+ * 1999-03-06 fl Moved declarations to separate file, etc.
+ * 1999-06-13 fl Changed join method semantics according to Tim's proposal
+ * 1999-08-10 fl Some minor tweaks
+ *
+ * Written by Fredrik Lundh, January 1999.
