Looks kinda like a localization failure. If you have e.g. Chinese in UTF-8 but mess up the output (or input) somewhere it tends to look something like that.
It looks like it's GB18030, HZ or GBK. At least those are the ones that render with no unknown characters. I don't read/speak any Chinese dialects so I've got no idea which two encodings are likely gibberish.
GB18030 is a superset of GBK. HZ is generally used on 7-bit only mediums like Usenet.
