You copy-pasted the program code using a tool (probably a web browser) that includes "funky" symbols in copied text. E.g. the non-breaking space.

One way to expose these characters is the following:

  1. Go to http://www.asciitohex.com/
  2. Copy-paste your code into the input box
  3. Click on convert
  4. Copy paste text from "Html Entities" output on lower right corner
  5. Remove all  -s and other strange things from code

\u160是不间断的空间。您是否尝试过删除并重新输入该行？
