zipfile模块解压zip文件中文乱码

在python2.7当中使用zipfile模块解压包含中文文件名的zip文件会出现奇奇怪怪的ASCII码拓展当中的字符
为此写了一个实现用于解决这一问题，主要是python2.7，由于2和3的编码问题，Python3应该不会这个问题（没具体测试过3解压中文会怎么样）

以下是实现，具体可以看看zipfile源码当中对于数据流的处理，很容易写出来
以下代码是从本人项目当中抽取出来稍作修改过后的，没有经过实际测试，如果有问题自行调试，总体处理方式应该是没有问题的。

def decompressChar(string, encode=None):
     try:
         if isinstance(string, unicode):
             string = string.encode("UTF8")
         elif encode is not None:
             string = unicode(string, encode)
         else:
             encodeTyp = chardet.detect(string)["encoding"]
             if encodeTyp is not None:
                 string = string.decode(encodeTyp).encode("UTF8")
     except UnicodeDecodeError as e:
         # 出现此错误一般为GBK编码涉及范围不及GB18030
         if 'gb2312' in e:
             string = string.decode('GB18030').encode("UTF8")
     return string


def zipfilePreprocess(zipfilePath, ):

    with zipfile.ZipFile(zipfilePath, ) as zipfileHandler:
        # 检查zip文件是否进行了加密,此处可以参考源码的实现(对于加密文件不做处理)
        # check zipfile whether encrypted or not(do nothing for encrypted file here)
        # refer -> zipfile source code line#983
        if filter(lambda x: x.flag_bits & 0x01, zipfileHandler.infolist()):
            return

        # 提取zip文件当中的各文件名和对应的文件内容,其实质上文件内容就是以字典结构存储在dict当中
        # Extract each file name and corresponding file content in the zip file
        members = [(f, member) for f, member in zipfileHandler.NameToInfo.iteritems()]
        for subFname, member in members:
            subFname = os.path.split(subFname)[-1]
            # change path by yourself, default current path
            subFilePath = os.path.join("./", decompressChar(subFname))
            # 通过文件写入的方式来对乱码处理,这是最关键的一步
            # 对于会出现zipfile模块解压zip文件乱码主要是winzip压缩的文件出现此类情况比较多,具体解释可以参考下面注释链接当中的内容说明
            # it is point for processing messy char
            # do not use zipfile.extractall() to unzip,otherwise filename,contained chinese, will be a mess after that. zipped by WinZip specially.
