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

This error happens when I try to run d:\linux\linuxkernel\android\内核\blog\BlogBackup(v1.1)source\html5lib-python-master\doc\make.bat. This may be because the chinese character or the path is too long. Then I try to run it as e:\1\html5lib-python-master\doc\make.bat, it works.
