Resolve Self.buf + = '. Join (self.buflist) Unicodedecodeerror: ' UTF8 ' problem

Problem

Return Self.outputBuffer.getvalue ()
  File "C:\Python27\lib\StringIO.py", line 276, in GetValue
    self.buf = "". Join (self.buflist)

Reason: View GetValue comments

    def getvalue (self): "" "
        Retrieve the entire contents of the" "File" at any time before the
        Stringio object ' s CL OSE () is called.

        The Stringio object can accept either Unicode or 8-bit strings, but mixing the two may
        take some. If both are used, 8-bit strings that cannot is interpreted as
        7-bit ASCII (that use the
        8th bit) would cause a UNIC Odeerror to being raised when GetValue () is
        called.
        "" " Import Chardet
        _complain_ifclosed (self.closed)
        if self.buflist:
            print type (self.buflist)
            Print "Buflist:", self.buflist
            # print "Detect:", Chardet.detect (self.buflist)
            self.buf + = '. Join ( self.buflist)
            print "BUF:", self.buf
            self.buflist = [] return
        SELF.BUF

The writing is very clear:

**the Stringio object can accept either Unicode or 8-bit strings,
But mixing the two may take some care. If both are used, 8-bit
Strings that cannot is interpreted as 7-bit ASCII (that use the
8th bit) 'll cause a unicodeerror to is raised when GetValue ()
Is called.**
Interpreted into Chinese:
Stringio objects can accept Unicode or 8-bit strings, but mixing the two may require careful

Solution:
Delete the following related statements

Print "__file__:", __file__
print "__file__:", Chardet.detect (__file__)

Because __file__ is the ' GB2312 ' code.
