Server

This example seperates an input string into single code points and then joins these back together, representing the original input string.

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

print( joined ) -- Hello World

Server

This example takes 3 code points to generate the string "MTA".

local mta = utf8.char( 77, 84, 65 )
print(mta) -- MTA

Client

This example takes the first 5 code points from the input string and then joins them back together.

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

local output = ""

-- Join the first 5 characters together
for index = 1, #codepoints do
    output = output .. utf8.char( codepoints[index] )
end

outputConsole(output) -- Multi
