Side-by-Side Comparison

Feature ASCII asti
Definition Norme longtemps utilisée pour le codage des caractères alphanumériques en informatique. À l’origine, utilisant sept bits, l’ASCII permet de représenter 128 caractères, numérotés de 0 à 127 et représentant 32 caractères de contrôle, l'espace et 95 caractères graphiques. L’ASCII dit « étendu » utilise le huitième bit de l’octet pour coder les caractères vernaculaires de 128 à 255, mais existe en plusieurs versions mutuellement incompatibles. L'UTF-8 est une forme d’ASCII dit « étendu » qui peut représenter chacun de ces caractères (voir Unicode). Variante de astic.
