What could go wrong in switching HTML encoding from UTF-8 to UTF-16?

Question

What are the implications of a change from UTF-8 to UTF-16 for HTML encoding? I would like to know your thoughts on the issue. Are there things I need to think of before m

Answer 1

There is also the byte order which becomes an issue with anything above 8-bit data. UTF encoded files begin with a byte order mark which is used to determine the byte order, or endianness, of that file.

Wikipedia has a quite good explanation of this.
