+/**
+ * ICU-internal class CStr, a small helper class to facilitate passing UnicodStrings
+ * to functions needing (const char *) strings, such as printf().
+ *
+ * It is intended primarily for use in debugging or in tests. Uses platform
+ * default code page conversion, which will do the best job possible,
+ * but may be lossy, depending on the platform.
+ *
+ * Example Usage:
+ *   UnicodeString s = whatever;
+ *   printf("%s", CStr(s)());
+ *
+ *   The explicit call to the CStr() constructor creates a temporary object.
+ *   Operator () on the temporary object returns a (const char *) pointer.
+ *   The lifetime of the (const char *) data is that of the temporary object,
+ *   which works well when passing it as a parameter to another function, such as printf.
