Guia ràpida
Què és ASCII?
ASCII is an encoding standard with 128 values, from 0 to 127. Each standard character has decimal, hexadecimal, octal and binary representations.
Text to ASCII decimal
Each character becomes its decimal value. For example, A is 65 and Hello is 72 101 108 108 111.
ASCII hexadecimal
Hexadecimal is a compact way to write ASCII bytes: A is 41 or 0x41.
ASCII binary
Binary shows each byte in eight bits. A is 01000001.
Printable and control characters
Values 32 to 126 are printable. Values 0 to 31 and 127 are controls, shown with labels such as [TAB], [LF] and [DEL].
ASCII versus Unicode
ASCII contains only 128 values. Unicode covers many more characters: ñ, €, emojis and non-Latin alphabets are not standard ASCII.
