Is there some sort of string pattern I can use to find, say, the 7th letter in a string?

string.gsub(strings, "(%w%w%w%w%w%w)(%w)(%w*)", "%1[[change here]]%3")--remove [[]]

......(.), blah It's still gross, I'd probably use string.sub twice and concatenate them all together.

Technically, it's more like function replace(s,n,r) return s:gsub("("..string.rep('.',n-1)..").","%1"..r); end
