hello

does any one know how to make an function that check if the string is ASCII characters or none ASCII characters?

!"#$%&'()*+,-./0123456789:;<=>?@ABCDEFGHIJKLMNOPQRSTUVWXYZ[\]^_`abcdefghijklmnopqrstuvwxyz{|}~ 

if is ASCII characters then it will returned true else false..

 function xxx(player,cmd,text) 
     if isASCII(text) then 
          outputChatBox("it's ASCII characters!",root) 
     else 
          outputChatBox("it's not ASCII characters!",root) 
     end 
end 
addCommandHandler("check",xxx) 
  
function isASCII(text) 
????? 
return true 
end

Maybe use string.find

Using a table containing all the ASCI character and using string.find inside a "for" , would do the job.

What do you mean?

If a string matches certain ascii code (string is a number) or what?

use one of these.

function isASCII(text) 
    for i = 1, #text do 
        local byte = text:byte(i) 
        if(byte < 33 or byte > 126)then 
            return false 
        end 
    end 
    return true 
end 
  
  
function isASCII(text) 
    -- used "\" before '"' as an escape char, otherwise it wont work. 
    local asciiTable = "!\"#$%&'()*+,-./0123456789:;<=>?@ABCDEFGHIJKLMNOPQRSTUVWXYZ[\]^_`abcdefghijklmnopqrstuvwxyz{|}~" 
    for i = 1, #text do 
        if not string.find(text, asciiTable[i], 1, true) then 
            return false 
        end 
    end 
    return true 
end

        if not string.find(text, asciiTable[i], 1, true) then 
            return false 
        end 
    end 
    return true 
end 

The first code works

Thanks for help
