字符的编码和解码

# Author:nadech
import sys
print(sys.getdefaultencoding())

#这里的s的编码方式还是unicode
s = "你好"

print(s.encode("gbk"))
print(s.encode("utf-8"))
print(s.encode("gb2312"))

#如果是utf8要转化成gbk
s_utf8 = s.encode("utf-8")
print(s_utf8)
print(s_utf8.decode("utf-8").encode("gbk"))
print(s_utf8.decode("utf-8").encode("gbk").decode("gbk"))
