Character Reference
What is ASCII?
ASCII (American Standard Code for Information Interchange) is a character encoding standard for electronic communication. ASCII codes represent text in computers, telecommunications equipment, and other devices.
Most modern character-encoding schemes are based on ASCII, although they support many additional characters. For example, UTF-8 is backwards compatible with ASCII for the first 128 characters.
Control Characters (0-31)
The first 32 characters are non-printing control codes used to control hardware peripherals. Famous examples include `NULL`, `Line Feed` (\n), and `Carriage Return` (\r).
Printable Characters (32-126)
These represent digits, uppercase and lowercase letters, and punctuation marks. 32 is the `Space` character, and 126 is the `Tilde` (~).
Decimal & Hex
Developers often need to convert between character representation and their numeric counterparts in different bases like Decimal (Base 10) or Hexadecimal (Base 16).
Extended ASCII (128-255)
Standard ASCII uses 7 bits. Extended ASCII uses 8 bits to provide 128 more characters like accented letters, currency symbols, and drawing characters.
