Certain Characters Of Strings

Questions
1

Is it possible to find out a certain character that’s in a string? Like by doing "Character[1] of “how” to get “h”? If so, how?

2

yep, google “lua string.sub”

function setup()
    str="abcedfghijklmnopqrstuvwxyz"
    print(string.sub(str,5,5))    -- single character
    print(string.sub(str,7,15))    -- range of characters
end

One thing to watch is that string.sub works on bytes not characters. This is fine if you are using ascii characters (and maybe latin, I don’t remember off the top of my head) but will get you in to trouble with proper unicode.

(Fortunately, I have a library for handling unicode strings if you need it.)
