There's some good (though advanced) stuff on the Lua Wiki:

http://lua-users.org/wiki/StringIndexing

E.g. you're shown how to get this:

-- demo
a='abcdef'
return a[4]       --> d
return a(3,5)     --> cde
return a{1,-4,5}  --> ace

So there you have it: one-byte substrings with square brackets,
to-from substrings with round, selected bytes with curly.
