ASCI Character Codes

Sep, 2025 | Web Development | 0 comments

What is ASCII?

ASCII stands for “American Standard Code for Information Interchange”. The primary reason behind the development of ASCII was for encoding text into a common format. Therefore, computers and humans can easily understand it. It has a unique code assigned to every character.

NOTE: Some characters are part of the Unicode character set, so you need to declare that in the head of your documents: <meta http-equiv="content-type" content="text/html;charset=utf-8" />

Types of ASCII Characters

The complete ASCII Table (from 0 to 255) includes different kinds of characters having their own implementation rules.

Control Characters: Characters ranging from 0 to 31 are known as unprintable control codes. They are used to controlling peripherals like printers.
Printable Characters: Characters ranging from 32 to 127 are known as printable characters. They are used in encoding letters, numbers, special characters, punctuation marks, and some symbols. Most of these characters are present on the keyboard.
Extended ASCII Characters: Codes ranging from 128 to 255 comes under the 8-bit called extended ASCII codes. These are high-end encoding characters that are based on adhering to the Windows-1252.

The standard ASCII table contains a total of 127 characters. It includes alphabets, digits, symbols, and control characters. Moreover, the extended ASCII code table contains a total of 255 codes and it’s used for higher-level encoding.

The extended ASCII table contains codes to fulfill the requirement of diacritics (the mark that we see above or along with the characters).

ASCII: Control Characters

Characters ranging from 0 to 31 are known as unprintable control codes. They are used to controlling peripherals like printers.
