Okay, I have solved this issue.
In the windows command line, I just type in "chcp", I know the default code page is 936, the gbk, an outdated standard of simplified Chinese character. and then I type in "chcp 65001, the code page is changed to 65001, the urf-8, which is preferable in python 3.x and elsewhere. If i type in chcp 437, I get American English code page. Furthermore, amazingly the alteration of the code page could be saved, so you don't have to set up each time.
In the command prompt opened in the Spyder, above-metioned approaches are feasible too.
Here is the link of information of the code page:
