This is a joke, right? This feels like a very dumb solution. I don't know much about UTF-8 encoding, but it sounds like Roman characters can be encoded shorter than most or all others because of a shorthand that assumes Roman characters. In that case, why not take that functionality and let a UTF-8 block specify which language makes up most of the text so that you can have that savings almost every time? I don't see why one would want it to be random.
