unichr(int(976918))

Answer 1

You can decode a string that has a Unicode escape (\U followed by 8 hex digits, zero-padded) using the "unicode-escape" encoding:

>>> s = "\\U%08x" % 976918
>>> s
'\\U000ee816'

>>> c = s.decode('unicode-escape')
>>> c
u'\U000ee816'

On a narrow build it's stored as a UTF-16 surrogate pair:

>>> list(c)
[u'\udb7a', u'\udc16']

This surrogate pair is processed correctly as a code unit during encoding:

>>> c.encode('utf-8')
'\xf3\xae\xa0\x96'

>>> '\xf3\xae\xa0\x96'.decode('utf-8')
u'\U000ee816'
