Hmm, I must be slow. I can't figure out how to convert a string with represented control characters into a string with actual control characters.
local input = [[ line 1\nline2 ]]
Into a string which will print like this:
For individual characters, this works:
But how can it be generic for all control characters?
str:gsub("\\(.)", '\%1') -- doesn't work
