Convert text, symbols, and emoji into Unicode escape sequences. Characters outside the Basic Multilingual Plane may appear as UTF-16 surrogate pairs.

Come funziona la codifica Unicode

Unicode assegna un codice numerico univoco a ogni carattere, simbolo ed emoji. Per esempio, la lettera latina A e U+0041, la lettera cirillica П e U+041F, e 😀 e rappresentato con coppie surrogate in UTF-16. Il convertitore trasforma i caratteri in queste rappresentazioni Unicode e li riconverte in testo leggibile.

Sicurezza e debolezze

Tutte le conversioni avvengono localmente nel tuo browser. Il tuo testo non viene caricato o salvato su un server.

Common Unicode Use Cases

Unicode conversion is commonly used in JavaScript, JSON, APIs, localization files, multilingual websites, text debugging, and source code where special characters need to be represented safely.

Developers often use Unicode escapes to inspect invisible characters, debug broken text, preserve multilingual strings, work with emoji, and safely represent characters that may be difficult to type or display directly.

Unicode vs ASCII and UTF-8

ASCII is an older character set that covers only 128 basic characters, mostly English letters, digits, punctuation, and control codes. Unicode is much broader and can represent characters from many languages, symbols, and emoji.

UTF-8 is a way to encode Unicode text as bytes. Unicode defines what each character means, while UTF-8 defines how those characters are stored or transmitted in binary form.

Unicode Escapes and HTML Entities

Unicode escapes such as \u041F are common in JavaScript, JSON, and source code. HTML entities such as © or © are commonly used in HTML documents.

Both formats can represent characters indirectly, but they are used in different contexts. Unicode escapes are common in programming languages, while HTML entities are designed for web markup.

FAQ

Unicode e uno standard universale di codifica dei caratteri che supporta testo da quasi tutte le lingue e sistemi di simboli.

Converte testo normale in sequenze Unicode escape e decodifica sequenze Unicode in testo leggibile.

Si. Unicode include emoji, simboli, caratteri matematici e molti alfabeti internazionali.

No. ASCII supporta solo caratteri inglesi di base, mentre Unicode supporta migliaia di caratteri di molte lingue.

No. Il convertitore funziona interamente nel browser e processa i dati localmente.

I caratteri fuori dal Basic Multilingual Plane, come gli emoji, usano coppie surrogate nella codifica UTF-16.

Si. Lo strumento supporta comuni sequenze Unicode in stile JavaScript come \\uXXXX.

A Unicode escape sequence represents a character using code notation such as \u0041 for A, \u20ac for the euro sign €, or \u2713 for the check mark ✓.

Unicode defines character code points, while UTF-8 is an encoding format that stores Unicode text as bytes.

Yes. The converter can decode common HTML entities and numeric character references back into readable text.

Many emoji are outside the Basic Multilingual Plane. In UTF-16, these characters are represented as two code units called a surrogate pair.
