I am upgrading from 1.54 to 1.55d. So far everything seems to be work fine. I read somewhere that UTF-8 mb4 can handle special characters better than the standard UTF-8 Unicode database format. I have searched everywhere for answers, and nobody talks about which UTF-8 format I should use.

Can I simply create a new "UTF-8 mb4 Unicode Ci" database and then import the old "UTF-8 Unicode Ci" tables into it?

I am wanting a web store that will be visible in different countries, and will allow different languages in the future. Is UTF-8 mb4 significantly better?
