Base64 encoding/decoding

[Oliver Kurz]

Hello,

I have a problem by converting a string to base64 and back again.

I have a string with german special chars like äöüß. 

This string i convert with base64str=base64.encode('äöüß') into a base64 representation.

Backwards I got an error:


binascii.Error: Incorrect padding

I use base64.decode(base64str).

The charset I use is iso-iso-8859-1. 

What am I doing wrong? 

Is there somewhere a good tutorial bei encoding and decoding with different charsets? 
I get text from different sources and i have to decode it and convert it at the end to utf-8.
