'ascii' codec can't decode byte 0xc4 in position 27: ordinal not in range(128)

This error happens when I try to run d:linuxlinuxkernelandroid内核logBlogBackup(v1.1)sourcehtml5lib-python-masterdocmake.bat. This may be because the chinese character or the path is too long. Then I try to run it as e:1html5lib-python-masterdocmake.bat, it works.
