Globalization Gotchas

I'm preparing a presentation for the next Unicode conference in March, 
and have been thinking about doing one on the pitfalls that people 
stumble into when using Unicode in globalizing software.

I have the following initial draft list, and would like to collect 
others. If you have any suggestions for additions or improvements, I 
would appreciate them. Please put "gotchas" in the subject field.
