the same thing you've missing in your other posts: value typing.

0xD3 is a Number, it's synonymous to 211, not to a byte, or a
character. 0xD3A8AF is also a number, synonymous to 13871279. even
worse, in Lua all numbers are floating point, so these are 211.0, and
13871279.0

if you want a three character string with each character specified in
hexadecimal, use:

string.char (0xD3, 0xA8, 0xAF)
