Python2.7检查文件是否用UTF8编码

Question

我目前的解决方案只是读取一个文件的所有字节，尝试解码，如果有任何异常，我会说这个文件没有正确编码。还有其他更优雅的方式吗？谢谢。在

utfbytes.decode('utf-8')

谨致问候， 林

However, some encodings are optimized for specific languages, and languages are not random. Some character sequences pop up all the time, while other sequences make no sense. A person fluent in English who opens a newspaper and finds “txzqJv 2!dasd0a QqdKjvz” will instantly recognize that that isn't English (even though it is composed entirely of English letters). By studying lots of “typical” text, a computer algorithm can simulate this kind of fluency and make an educated guess about a text's language.

但是，存在的some libraries确实尽了最大努力尝试找到编码类型。在
