To help both in Chinese or English you can specifiy the page language
HTML 4.01
<head lang="en-US">
XHTML
<html xmlns="http://www.w3.org/1999/xhtml" lang="en" xml:lang="en">
lang="en" twice is the attribute default namespace binding to the element and the attribute key.
I don't know what it is in Chinese but you can look it up at

Note: You probably accidently saved your page in "unicode",
A character byte for UTF-8 contains 8bits but if it were unicode or UTF-16
then it would contain 2 bytes p/character (hence the space and its really
a character that has no visible font descriptor for the machine data number
and the bytes are being read and assembled by the browser as single byte
because of the declaration).
