Python2未知编码字符串转为utf-8编码

Python的编码问题总是非常烦人，一不小心就出来乱码，本函数采用的方法为：分别用try判断是否能解码成功，如果能成功表明为相应编码，解码成功后再编码为utf-8，代码如下：

# -*- coding: utf-8 -*-

def to_utf8(data):
    try:
        # print("Trying decode with utf-8 ...")
        data_de = data.decode("utf-8")
        # print("Use utf-8 decode success")
        # print("Trying encode with utf-8 ...")
        # data = data_de.encode("utf-8")
        # print("Use utf-8 encode success\n")
        return data
    except:
        # print("Use utf-8 decode failed\n")
        pass

    try:
        # print("Trying decode with ascii ...")
        data_de = data.decode("ascii")
        # print("Use ascii decode success")
        # print("Trying encode with utf-8 ...")
        data = data_de.encode("utf-8")
        # print("Use utf-8 encode success\n")
        return data
    except:
        # print("Use ascii decode failed\n")
        pass

    try:
        # print("Trying decode with gbk ...")
        data_de = data.decode("gbk")
        # print("Use gbk decode success")
        # print("Trying encode with utf-8 ...")
        data = data_de.encode("utf-8")
        # print("Use utf-8 encode success\n")
        return data
    except:
        # print("Use gbk decode failed\n")
        pass

    try:
        # print("Trying decode with utf-16-le ...")
        data_de = data.decode("utf-16-le")
        # print("Use utf-16-le decode success")
        # print("Trying encode with utf-8 ...")
        data = data_de.encode("utf-8")
        # print("Use utf-8 encode success\n")
        return data
    except:
        # print("Use utf-16-le decode failed\n")
        pass

    # 如果以上几种都不能解码成功，返回传过来的字符串
    return data
