Should I change from UTF-8 to UTF-16 to accommodate Chinese characters in my HTML?

I am using ASP.NET MVC, MS SQL and IIS. I have a few users that have used Chinese characters in their profile info. However, when I display this information is shows up as æŽå¼·è¯ but they are correct in my database. Currently my UTF for my HTML pages is set to UTF-8. Should I change it to UTF-16? I understand there are a few problems that can come from this but what are my choices?
