ASCII (American Standard Code for Information Interchange) ist ein 7-Bit-Zeichencodierungsstandard, der 128 Zeichen auf die Ganzzahlen 0–127 abbildet. Er umfasst Steuerzeichen (0–31), druckbare Zeichen (32–126) und das DEL-Zeichen (127).
ASCII kodiert 128 Zeichen mit 7 Bit. Unicode ist eine Obermenge, die über 140.000 Zeichen aus allen Schriftsystemen der Welt kodiert. ASCII ist vollständig mit UTF-8 Unicode kompatibel — die ersten 128 Codepunkte sind identisch.
Steuerzeichen (0–31) sind nicht druckbare Codes, die steuern, wie Text verarbeitet wird. Gängige Beispiele sind NUL (0), TAB (9), LF/Zeilenumbruch (10), CR/Wagenrücklauf (13), ESC (27) und DEL (127).
Verwenden Sie dezimale Entitäten wie A für A oder hexadezimale Entitäten wie A für A. Für Sonderzeichen werden benannte Entitäten wie & für & bevorzugt, wenn verfügbar.
