Write decoded from base64 string to file

Question

the question is that how to write string decoded from base64 to a file? I use next piece of code:

import base64

input_file = open('Input.txt', 'r')
coded_string = input_file.read()
decoded = base64.b64decode(coded_string)
output_file = open('Output.txt', 'w')
output_file.write(decoded)
output_file.close()

Input.txt contains base64 string (smth. like PD94bWwgdmVyc2lvbj0iMS4wIiBlbmNvZGluZz0iVVRGLTgiPz48cmV2aW). After script execution I suppose to see xml in Output.txt but output file contains some wrong symbols (like <?xml version="1.0" encoding="UTF-8"?><review-case create®vFFSТ#2). At the same time if I not read from base64 string from file Input.txt but specify it in script as coded_string = '''PD94bWwgdmVyc2lvbj0iMS4wIiBlbm...''' then Output.txt contains correct xml. Is this something wrong with utf encoding? How to fix this? I use Python2.7 on Windows 7. Thanks in advance.

You probably figured out of to do that now 5 years later, but here is the solution if anyone needs it.

import base64

with open('Input.txt', 'r') as input_file:
  coded_string = input_file.read()
decoded = base64.b64decode(coded_string)
with open('Output.txt', 'w', encoding="utf-8") as output_file:
  output_file.write(decoded.decode("utf-8"))
