Fido "Can't convert 'bytes' object to str implicitly" in Python 3.4/3.5

[RvanVeenendaal]

Hi,
As a new user of Fido, I ran into the error message from the subject while analysing Fido's README.txt on:

• Windows 8.1 Enterprise (64 bits)
• Python 3.4
• Fido 1.3.4
  The problem seems related to differences between Python 2 and 3 (Unicode handling).
  If I use Python 2.7.11, Fido works just fine ("Plain Text File").
  If I use Python 3.5.1, I get the same error message.
  See below for more details.

c:\fido>fido

[FILE [FILE ...]]
(etc. - Fido seems to have been installed properly)
