ASCII (American Standard Code for Information Interchange) is a character encoding standard that assigns numbers to English letters, digits, punctuation marks, and control characters. b = 98. Using charCodeAt() to Get Unicode ValuesThis code defines a string letter containing the character "A". Unicode; ASCII bassically used to represent text in form of symbols, numbers, and character: UNICODE is used to exchange, process, and store text data in any language: The purpose of this article is to get the ASCII code of any character by If for some strange reason you have an ASCII code unit, you can easily convert it by relying on 1) ASCII code unit are the same as ASCII codepoint, 2) ASCII codepoints are the same as Unicode codepoints (for the characters in common), 3) UTF-16 encodes those characters in one UTF-16 code unit, and 4) those UTF-16 code units, although having 16 Unicode has become the de facto standard for character encoding in modern computing and has largely replaced older encoding standards, such as ASCII. So it must be \u00fc (6 characters) not the character itself. 1. Encoding for characters maps up to 128 unicode characters to the ASCII codes 0x80 to 0xFF.
