-8 to encode Chinese characters. 2.python encoding and decoding of characters Character encoding/decoding function: 1 Unicode: This is Python's built-in function, located in the Unicode class. Unicode (string [, encoding[, Errors]])-> object The purpose of this function is to encode a string as a Unicode object in encoding format. Omitting parameters will be decoded with Python's default ASCII 2) Decode: is located in the Unicode class. Decode (...)| S.decode ([encoding[,errors]])-> string or

Issue:unicodedecodeerror: ' gb2312 ' codec can ' t decode bytes in position 2-3: illegal multibyte sequenceCause: Python is doing a normal string conversion to a Unicode object.For example: u_string = Unicode (String, "gb2312"), if you have strings in string such as some traditional characters, such as " River Kau Primary School "in the Kau, then gb2312 as Simplified Chinese encoding is not resolvable, you must use the GB extension code GBK,GBK suppo

When writing a file using Python, or when writing a network stream to a local file, in most cases you will encounter: Unicodeencodeerror: ' GBK ' codec can ' t encode character ' \xa0 ' in position ... The problem. There are a lot of similar files on the network about how to solve this problem, but nothing is encode,decode related, is this the real cause of the problem? No. Many times, we used decode and encode, tried all kinds of code, utf8,utf-8,gbk

prediction. The principle is to use the past several samples values to predict the current value. The more the past values are used, the closer the predicted value to the actual value. Encode the difference value between the real value and the predicted value, which further reduces the number of quantified bits. There are three models for predicting the current time series value: Ma model-Moving Average Model, AR model-Self-regression model, ARMA model-auto-regression moving average model.

Django view functions often encounter errors similar to 'ascii 'codec can't decode byte 0xef in position 0: ordinal not in range (128. Before resolving the error, you must first understand the difference between Unicode and UTF-8.Unicode refers to a world code table ". UTF-8 is the encoding method stored in this code table. Unicode does not have to be compiled into bytecode storage by UTF-8. You can also use other methods such as UTF-16 and utf-7. At

Previously, we used speex encoding and decoding in applications. Recently, we have summarized the implementation of speex on Android. Speex is an open-source, free, and patent-free audio compression format. The speex project strives to reduce the input threshold of speech applications by providing an alternative high-performance speech codec. In addition, compared with other codec, speex is also suitable fo
