Python字串轉換成Unicode--比較好用的方法

將Python字串轉換成Unicode

plainstring1 = unicode(utf8string, "utf-8")
plainstring2 = unicode(asciistring, "ascii")
plainstring3 = unicode(isostring, "ISO-8859-1")
plainstring4 = unicode(utf16string, "utf-16")

先用type函式確定一下是什麼編碼的
str編碼是"utf-8"

另外，
將Unicode轉換為其他編碼

utf8string = unicodestring.encode("utf-8")
asciistring = unicodestring.encode("ascii")
isostring = unicodestring.encode("ISO-8859-1")
utf16string = unicodestring.encode("utf-16")
