AS3 - Multi language site
I need to build a multi language site with the following languages: 

> English, Spanish, Portuguese, German, French and Chinese

If a user is from a country where the language is not available like Italy - which language should be displayed then?
 
Also I was wondering which language should be displayed for countries like Canada or Switzerland where more than 1 language is the national language?
