A style sheet has two bugs @ charset in earlier Google versions.

Because of program goals, cssis used for sasscompilation. After compilation and completion of global.css and style.css, no problems were found in the local test. I thought this project was done successfully, but after being put online, a huge bug occurred. With the help of colleague Cheng moumou, find the cause of the problem

1. If Sass is automatically converted to CSS, @ charset = "UTF-8" is automatically added"

2. After the two style sheets are merged and compressed, two @ charset = "UTF-8"

3. embedded with support for earlier versions of WebKit kernel software, a major bug occurs.
