Unicode?

[kee nethery]

I have to delve into the world of Unicode. Is there a sample stack or  
set of sample stacks that people would recommend that I start with?

In specific I'll grab unicode from a database via HTTP POST, display  
it in a field, allow it to be edited, and then save the results back  
into the database using HTTP POST.

I get the feeling from all I have read on this list that unicode is a  
mind field of things that do not work as expected or as documented.

Thanks,
