What is the difference between AL32UTF8 & WE8MSWIN1252 DB character sets ?

We have two ALM DBs one with WE8MSWIN1252 and another with AL32UTF8 character sets. So which DB is now unicode enabled one that supports all the regional languages like Japan, French, Spanish etc along with the English language. Is it AL32UTF8 or WE8MSWIN1252 ?
