gbk,unicode,ASCII,utf-8,utf-16编码转换

将unicode转化为普通Python字符串:”encode”

demo = u”Hello world”
utf8string = demo.encode(“utf-8”)
asciistring = demo.encode(“ascii”)
isostring = demo.encode(“ISO-8859-1”)
utf16string = demo.encode(“utf-16”)

将普通python字符串转化为Unicode:”decode”

demo = unicode(utf8string,”utf-8”)
demo = unicode(asciistring,”ascii”)
demo = unicode(isostring,”ISO-8859-1”)
demo = unicode(utf16string,”utf-16”)
