[plt-scheme] servlet, character encoding of data file contains sexps

I was playing with the web-server's useful quiz.ss, and I made a  
chinese-questions.ss from english-measure-questions.ss.  I have some  
lists with Chinese characters in them, e.g.:

	("你" "泥" "拟" "呢")

I gather I should stick with UTF-8 encoding?  The servlet didn't seem  
to like reading a file containing UTF-16.
