From: "Martin":
In description of string module maybe there should be explicitly noted that string.byte string.char string.len (perhaps other functions too) works intuitively only with ASCII encoding. With utf-8 encoding that I have set on my computer results are strange. I do not know how they work under Windows Unicode charset.
My manual states the above clearly: "string.byte (s [, i [, j]])Returns the internal numerical codes of the characters s[i], s[i+1], ···, s[j]. The default value for i is 1; the default value for j is i.
Note that numerical codes are not necessarily portable across platforms."The same is said for string.char. Or do you mean to say string.char(string.byte('!')) does not work as expected?
I do agree about the fmod thing though, as the difference between "modulo" and "remainder" is not well defined.
