Str,unicode and gb2312 in Python

Example 1:

V1=u ' good magic question!? '

Type (v1)-"Unicode

V1.decode ("Utf-8") # Work,because V1 is Unicode already

V1.encode ("gb2312") #work, convert from Unicode to gbk2312

Found

Decode is the conversion of the specified object to Unicode (Unicode contains utf-8,utf-16) and indicates how the object to be converted is encoded.

Encode is the process of translating Unicode objects into other encodings.

Example 2:

V1=r ' C:\abc\1.txt '

V2=r ' good magic question '

V3=r ' C:\abc\12dc\ text-txt '

V4=r ' \\rdf\azzwang\maya2013 project\imageshahah\ æ refer Chuan lu cun trajectory. jpg '

	. Decode ("Utf-8")	. Decode ("gb2312")
V1	√	√
V2	X	√
V3	X	√
V4	√	X

Found

For a string of type str, if you want to use Utf-8 to decode it is completely impossible. Therefore, we expect a method of a program to return a specific encoding (such as Unicode), in which case we can use the Encode method directly into the encoding we want, without having to decode the puzzle.
