Determining if two strings are "almost the same" is not easy.  If míguel 
and miguel are to be considered the same, then why not also consider 
michael to be the same?  Or, for that matter, mike, mikey, or mick?  
There's no easy answer, and what's the right answer for some 
applications will be the wrong answer for others.
