Sorry for the typo.  Yes, the term supermajority (first known use almost a thousand years ago) is used in "international English" to refer to any vote where more than a true majority (50%+1) is required.  And then there is "international English's" 'simple majority'--which includes minorities that we know as pluralities.  
I don't have time to do pedantic work for this, such as listing 'other nations'.  Germany comes first to mind, of course, but you can find such nations via Google yourself.
