codecs
python的编码解码器coder/decoder。
import codecs
# 使用注册名为encoding的编码器编码obj，encoding默认为ascii。
# encode将unicode编码的obj编码成encoding编码对应的字节序列．
codecs.encode(obj, [encoding[,errors]])
codecs.encode(u'hello world', 'utf-8') # 编码成utf-8字节序．
# 使用注册名为encoding的解码器解码obj，encoding默认是ascii。
# decode将原来按照encoding编码的obj解码成unicode字符串.
codecs.decode(obj, [encoding[,errors]])
codecs.decode(obj, 'utf-8') # 将utf-8编码的obj解码成unicode.
# encoding取下面值:
# ascii是默认值,gb2312, gbk, gb18030, utf-8, utf-16
# ascii利用一个字节把字符转换成数字．
# unicode利用多字节转换，支持多种编码方式，utf-8, uft-16.
# errors取下面值：
# strict, 默认值，抛出UnicodeError异常。
# ignore
# replace
# xmlcharrefreplace
# backslashreplace
