JavaScript code doesn't work in chrome. I gives me an error:
VM180:1 Uncaught SyntaxError: Invalid or unexpected token
When I see on console in chrome, all my code is written in Chinese, but in my code file, it is written in English.

Just like any other text file,
.jsfiles have specific encoding they are saved in. This message means you are saving the.jsfile with a non-UTF8encoding (probably ASCII), and so your non-ASCII characters never even make it to the disk.While saving files from your Text Editor, you'll have to change the encoding of the file, choose UTF-8 without saving a Byte Order Mark (BOM).
