He can still store the repr of the string into the database, and then
reconstruct it with eval:

>>> bytes = "\x00\x01\x02"
>>> bytes
'\x00\x01\x02'
>>> len(bytes)
3
>>> ord(bytes[0])
0
>>> rb = repr(bytes)
>>> rb
"'\\x00\\x01\\x02'"
>>> len(rb)
14
>>> rb[0]
"'"
>>> rb[1]
'\\'
>>> rb[2]
'x'
>>> rb[3]
'0'
>>> rb[4]
'0'
>>> bytes2 = eval(rb)
>>> bytes == bytes2
True
