[issue22999] Copying emoji to Windows clipboard corrupts string in Python 3.3 and up

[Amaury Forgeot d'Arc]

Amaury Forgeot d'Arc added the comment:

(you swapped the unicode values: \U0001f4cb is copied as \U0001f400)

On Windows, strings have changed in 3.3. See in https://docs.python.org/3/whatsnew/3.3.html, "len() now always returns 1 for non-BMP characters".

The call to GlobalAlloc should use the number of wchar_t units, something like len(data.encode('utf-16')) + 2
