It was saved in a file, so it occupy 36 bytes. If I just use a
variable to contain this string, it can certainly work out correct
result,but how to get right answer when reading from file.

You are right , the result is 日期 which I just expect. If you save the
string in a variable, you surely can get the correct result. But it is
just a sample, so I give a short string, what if so many characters in
a file?

I have tried this method which you just told me, but unfortunately it
does not work(mess code).

My Python versoin is 2.5.2

The result is:

def UTF8ToChnWords():
    f = open("123.txt","rb")
    print repr(content)
    print len(content)
    print content.count("\\")
    print content.count("x")

if __name__ == '__main__':

It doesn't work because no matter in what way we deal with it we often
get 36 bytes string not 9 bytes.Thus, we can not get the correct
