missing codec

An error message occurred while reading a file using Python3Unicodedecodeerror: ' GBK ' codec can ' t decode byteThis is due to Python in the decoding process error, all character encoding in Python3 is Unicode encoding, and in the file to be read in Chinese, which is beyond the GBK encoding representation range, GBK encoding can not decode it, so error.After some Baidu, find the following solutions:1. Set the encoding when opening the file, such as:

When Python is installed, the default encoding is ASCII, and when non-ASCII encoding occurs in the program, Python processing often reports such an error unicodedecodeerror: ' ASCII ' codec can ' t decode byte 0x?? In position 1:ordinal No in range (128) There are 2 ways to set Python's default encoding: Method One: Add the following code to the program: Import sys reload (SYS) sys.setdefaultencoding (' UTF8 ') method two: In the Python installation d

PDU codec details Brief Introduction SMS is a specification developed by ETSI (GSM 03.40 and GSM 03.38 ). It can send up to 160 characters, when using 7-bits encoding. 8-bit encoding (up to 140 characters) is usually not displayed directly through the mobile phone; it is usually used as a data message, such as pictures and ringtones in smart messaging) and ota wap settings. 16-bit information (up to 70 characters) is used to display Unicode (ucs2) tex

It is a kind of encoding with the highest quality requirement. It is a non-linear system. Therefore, it tries its best to use the jitter algorithm during the Encoding Process (you can also set it to not shake) to simulate the effect of the true color. This algorithm is alm
