ServerThis example separates an input string into single codepoints 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

ServerThis example takes three code points to generate the string "MTA".
local mta = utf8.char( 77, 84, 65 ) print( mta ) -- MTA

ClientThis example takes the first five 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
