string.byte

Return the byte of the first character in the given str. As string literals in Lua represent ASCII strings, this will most likely return ASCII codepoints. To convert a byte back into a string, use string.char.

ExamplePrint the bytes of the user input
Read a character from the user, then print the byte of each letter, separated by spaces.
Code 
<nowiki>
for character in read():gmatch(".") do
  write(string.byte(character))
  write(" ")
end
    </nowiki>
Output Depends on what the user wrote. For instance, if they were to enter Hello World, the output would be 72 101 108 108 111 32 87 111 114 108 100.
