Python 2.7. Unicode Errors Simply Explained

I know I'm late with this article for about 5 years or so, but people are still using Python 2.x, so this subject is relevant I think.

Some facts first:

• Unicode is an international encoding standard for use with different languages and scripts
• In python-2.x, there are two types that deal with text.
  1. str is an 8-bit string.

2. unicode is for strings of unicode code points.
