Inspector de Unicode
Inspecciona cada carácter de una cadena, identifica caracteres invisibles, consulta los puntos de código y normaliza el texto a NFC, NFD, NFKC o NFKD.

How to inspect Unicode text
Reveal the code points behind a string so invisible characters, combining accents, emoji, and look-alike text are easier to diagnose.
Reading the table
Each visible row represents one Unicode code point from the input. The table shows the character, its U+ value, a broad category, and a name when the runtime can provide one.
Invisible characters
Tabs, line feeds, no-break spaces, zero-width spaces, joiners, and similar characters are marked as invisible. These characters often explain why search, copy/paste, alignment, or validation behaves strangely.
Normalization buttons
- NFC composes characters when possible, turning many letter-plus-accent sequences into a single code point.
- NFD decomposes characters into base letters plus combining marks.
- NFKC and NFKD also fold compatibility characters, which can change symbols and full-width forms more aggressively.
When to use it
- Debug text that looks identical but fails equality checks.
- Find hidden zero-width or no-break characters in copied content.
- Compare composed and decomposed accented text before storing or matching it.
- Inspect emoji, symbols, and punctuation that may not be obvious by sight.
Content handling
Normalization changes the text in the input field. Copy the original elsewhere first if you need to compare before and after carefully.
Preguntas frecuentes
Why does Café sometimes show as more than one character?
The accent can be stored as a separate combining mark after the letter. NFC usually composes that into one precomposed character when Unicode has one available.
What does invisible mean here?
It means the code point has little or no visual width, such as a tab, line feed, no-break space, zero-width space, or joiner. It can still affect matching, layout, and cursor movement.
Why does the name say it is not available?
Browsers do not expose a full Unicode name database to JavaScript. The tool names common controls, spaces, ASCII letters, and digits, then falls back when no name is available.
Can normalization change what users see?
Yes, especially with NFKC and NFKD. They can fold compatibility characters such as full-width letters or special symbols, so review the text after applying them.
