代码中的一些编码细节

编码问题：

UnicodeDecodeError: 'utf-8' codec can't decode byte 0x80 in position 0: invalid start byte

pickle.load(open(fname_or_dict, ‘rb’）—可以解决;

UnicodeDecodeError: 'ascii' codec can't decode byte 0x81 in position 1224: ordinal not in range(128)

pickle.load(open(fname_or_dict, ‘rb’), encoding=“iso-8859-1”)

问题就可以解决！！
