"""
Test various clipboard solutions (for Windows).

2014-12-04 v1.1 use locale.getpreferredencoding()
2014-12-05 v1.2 Test emoji. pyperclip (1.5.5) now uses the ctypes code.
2014-12-05 v1.3 ctypes code now uses proper CF_UNICODETEXT encoding according to http://bugs.python.org/issue22999#msg232191 - Emoji 📋 (\U0001f4cb) was copied as 🐀 (\U0001f400) in Python 3.3+.
