local codepoints = { utf8.byte( input, 1, utf8.len(input) ) }
local joined = utf8.char( unpack(codepoints) )
print( joined ) -- Hello World

local input = "Mutli Theft Auto"
local codepoints = {}
-- Extract first 5 characters (read: Mutli)
for index = 1, 5 do
codepoints[index] = utf8.byte( input, index )
end

for index = 1, #codepoints do
output = output .. utf8.char( codepoints[index] )
end
