"""Return the hexadecimal representation of the binary data. Every byte of 
data is converted into the corresponding 2-digit hex representation.
"""

makes it pretty clear that the function is operating on bytes, not str.

The following sentence "The resulting string..." is likely a leftover from 
Python 2 and should be fixed.

If you need str instead of bytes it's easy enough to do the 
encoding/decoding yourself:

>>> import binascii as ba
>>> ba.hexlify("äöü".encode())
b'c3a4c3b6c3bc'
>>> ba.unhexlify(_).decode()
'äöü'
