Usage Guide

ASCII Overview

!ASCII (American Standard Code for Information Interchange) is a character encoding standard based on the Latin alphabet, primarily used for modern English and Western European languages. ASCII defines 128 characters (codes 0-127), including 33 control characters (0-31 and 127) and 95 printable characters (32-126).

Character Classification

!Control characters (0-31, 127): non-printable, used to control devices (e.g., newline \n, carriage return \r, tab \t, etc.); Printable characters (32-126): include space, digits 0-9, uppercase A-Z, lowercase a-z, and punctuation symbols.

How to Use

In the Character-Code Conversion area, enter a character to see its decimal, hex, octal, and binary codes; enter a code (decimal, hex 0x, or octal 0o) to see the corresponding character. Use the search box to quickly find specific characters or descriptions. Clicking a row in the printable table auto-fills the conversion area.
