2.5. 字符编码相关的函数

此代码中是判断是否大于0.5来决定是否是可能的字符串类型。使用者可根据自己需要，改为自己想要的概率，比如0.8等。

#------------------------------------------------------------------------------
# get the possible(possiblility > 0.5) charset of input string
def getStrPossibleCharset(inputStr) :
    possibleCharset = "ascii";
    #possibleCharset = "UTF-8";
    encInfo = chardet.detect(inputStr);
    #print "encInfo=",encInfo;
    if (encInfo['confidence'] > 0.5):
        possibleCharset = encInfo['encoding'];
    return possibleCharset;
    #return encInfo['encoding'];
        

validCharset = getStrPossibleCharset(dataJsonStr);
logging.debug("Now try use the detected charset %s to decode it again", validCharset);
