chrome从版本55开始，不再支持设置网页内容编码

Hi Everyone,

Chrome 55 has removed the Encoding menu and Chrome will do auto-encoding detection now:

https://bugs.chromium.org/p/chromium/issues/detail?id=597488  -  Remove encoding menu

Manual encoding selection is not necessary any more as the new encoding detector is turned on by default.

Manual encoding switching may be able to be done by use of Chrome extensions.

虽然不再支持,但是可以使用相关的chrome扩展设置。
