python混账的编码问题解决之道

import codecs

def ReadFile(filePath, encoding):
    with codecs.open(filePath, "r", encoding=encoding) as f:
    return f.read()

def WriteFile(filePath, content, encoding):
    with codecs.open(filePath, "w", encoding=encoding) as f:
    f.write(content)

def UTF8_to_GBK(src, dst):
    content = ReadFile(src, encoding="gbk")
    WriteFile(dst, content, "utf-8")
