Hi
1) Double byte supports Japanese and Chinese and Korean Characters so of
you have to support entry in one of those then you will need double byte
single byte is basically for everything else
2) To create a database double byte enabled you need to select some
options like characterset support for your database
This link will pretty much answer all your questions
