Tchaikovsky was stored as 'Пётр Ильи́ч Чайко́вский'. As you might expect, this turned out to be a bad idea on many levels:
* No searching
* Always ends up on the top/bottom of alphabetically sorted lists
* Took much longer to work out which artist it was because I'm not fluent in Cyrillic
* The Microsoft Zune's fonts did not support most non-ASCII characters (this was a big one!)
That being said, I was young and it looked cool, so I kept it :)
