Domande Frequenti

Cos'è l'ASCII?

L'ASCII (American Standard Code for Information Interchange) è uno standard di codifica dei caratteri a 7 bit che associa 128 caratteri agli interi da 0 a 127. Include caratteri di controllo (0-31), caratteri stampabili (32-126) e il carattere DEL (127).

Qual è la differenza tra ASCII e Unicode?

L'ASCII codifica 128 caratteri usando 7 bit. Unicode è un superset che codifica oltre 140.000 caratteri da tutti i sistemi di scrittura del mondo. L'ASCII è completamente compatibile con UTF-8 Unicode — i primi 128 punti di codice sono identici.

Cosa sono i caratteri di controllo ASCII?

I caratteri di controllo (0-31) sono codici non stampabili che controllano come viene elaborato il testo. I più comuni includono NUL (0), TAB (9), LF/a capo (10), CR/ritorno a capo (13), ESC (27) e DEL (127).

Come si usano i codici ASCII in HTML?

Usa entità decimali come A per A o entità esadecimali come A per A. Per i caratteri speciali, le entità nominate come & sono preferite quando disponibili.
