ASCII code is what, the ASCII comparison table

ASCII (American Standard Code for Information Interchange, American Information Interchange standard codes) is a computer coding system based on the Latin alphabet. It is mainly used to display modern English and other Western European languages. It is the most common single byte coding system today, and is equivalent to international standard ISO/IEC 646. The following is the ASCII code table, I hope to he

"Reprint" Ascii,unicode,utf-8 and Python3 character encoding

CodingA string is a data type, but a particular string is a coding problem.Because a computer can only handle numbers, if you are working with text, you must convert the text to a number before processing it. The oldest computer was designed with 8 bits (bit) as a byte (byte), so a single word energy-saving representation of the largest integer is 255 (binary 11111111 = decimal 255), if you want to represent a larger integer, you must use more bytes. For example, two bytes can represent the larg
