回答1:

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

回答2:

\u160 is the non-breaking space. Have you tried deleting and retyping the line?
