A detailed description of the character coding problems that Python often appears

The encoding error often occurs when Python is doing string processing or reading a file through the Open function: unicodedecodee-rror: ' ASCII ' codec can ' t decode byte 0xe6 in position 0: Ordinal not inRange (128) This is due to the error that occurs when the codec is not compatible with Python during encoding and decoding. So now it is necessary to have a clear understanding of the character encoding, do not need to the internal content of the codec in-depth study, only need to understand

This design allows literal and length to share the same Huffman tree, once encoded at the same time to get literal and length code word. The range of literal is the closed interval [0, the 255],length range is the closed interval [3, 258]. Compression combines the two intervals into the same table to bring them together. The closed interval [0, 255] still represents the literal, the relationship is one-on-one, a number corr
