Solve the following python programming problem given the following code:
def CUnescape(text) : 
    'Unescape a text string with C-style escape sequences to UTF-8 bytes.' 
    def ReplaceHex(m) : 
        if (len (m.group (1)) & 1) : 
            return ((m.group (1) + 'x0') + m.group (2)) 
return m.group (0) 
result = _CUNESCAPE_HEX.sub (ReplaceHex, result) 
    if (sys.version_info [0] < 3) : 
        return result.decode ('string_escape') 
result = ''.join ((_cescape_highbit_to_str [ord (c)] for c in result)) 
    return result.encode ('ascii').decode ('unicode_escape').encode ('raw_unicode_escape') 

    
    

    Fix the buggy line: result = _CUNESCAPE_HEX.sub (ReplaceHex, result)

#Here is Python program to fix the buggy line: result = _CUNESCAPE_HEX.

result = _CUNESCAPE_HEX.sub (ReplaceHex, text)
