Confused about RSS encoding

[kfegarty]

I am coding our xml file and I am confused when I look at others - some I see the first line as encoding="iso-8859-1"?
others
encoding="windows-1252"?

or

encoding="UTF-8"?

What should I use? What is the difference?

[Faglork]

UTF-8 is the choice, with iso-8859-1 as second option.
