  • Dreaded python encoding errors, how to stop them?

    - by Rhubarb
    These have been plaguing me endlessly. Why? It seems that my console can't handle the encoding. I take it that the my browser and word processor can handle it. I don't have a master list of all the possible characters that it's choking on. What is the best way to relieve this without modifying my data? 'charmap' codec can't
