BTW: your code is flawed. Feed it some of the stuff near the end of this 
post and it will fail:

tl;dr; your code doesn't slice on characters but something called (IIRC) 
code points. If you start worrying about diacritic (and many end user 
will want you to)
you need to do a bunch more processing.
