Well there's more than that, there's also some special characters. I'll see if I find the topic with the answer, as I've seen it here in AaP.

But within computercraft? I mean i have ran a loop that converts to bytes the iteration number so i tested from 0 to (more or less) 500 and i only got displayable characters within the range of 32-126. So you mean there is more? I know that you can write to a file and use charachters like Á, Ã, Â if you use a text editor, and i also know you can save the returned value of, example: string.char(128) and save it to a file, but nothing more. I will wait for your response, because if we can use more characters that would be awesome.

From what i know string.char() will return a string with the chars corresponding to each byte given in the arguments. So i don't think that helps much. :P/>

From what I remember, the person from the topic did something like this to get the special characters

string.char( 195, 63 )

Note: I've just put in random numbers :P/>
