I've updated my tutorial All About Python and Unicode again. It is now fully integrated into Drupal instead of being a standalone HTML document (in a different style and without the ability to add comments ... how 1995!). With this revision I've tried to clarify the section about splitting up Unicode strings, explaining a little more about why it is needed. Enjoy!

Update (2007-03-06): Oops, forgot the table of contents ... added.
