There's nothing wrong with Unicode. UTF-8 sucks because it ends up taking more space.
@byuu No it doesn't. Try compressing a SJIS text using gzip. Then convert it to UTF-8 and do the same thing. With a "perfect" compressor, there shouldn't be any difference since the information contents are the same, but unfortunately we don't have a perfect compression algorithm that hits the theoretical lower bound for compression.
