On UNIX, data going outside Python has be be encoded: you pass byte strings,
not directly Unicode. Surrogates are encoded back to original bytes.
Example:
>>> b'a\xff'.decode('ascii', 'surrogateescape')
'a\udcff'
>>> b'a\xff'.decode('ascii', 'surrogateescape').encode('ascii',
>>> 'surrogateescape')
b'a\xff'
