👁️ Herramienta de caracteres invisibles

Los caracteres invisibles, como los espacios de ancho cero, los espacios de no separación o una marca de orden de bytes (BOM), se cuelan a menudo en el texto copiado y provocan problemas difíciles de detectar en la visualización, la búsqueda y el procesamiento de datos. Esta herramienta analiza tu texto, muestra cada carácter oculto con su posición, su punto de código Unicode y su nombre, y puede eliminarlos todos con un clic. El procesamiento se realiza íntegramente en tu navegador.

How to Use This Tool

Pega tu texto en el campo y pulsa «Detectar caracteres». Verás una tabla con todos los caracteres invisibles encontrados. Con «Eliminar y limpiar» obtienes una versión limpia lista para copiar.

What This Tool Checks

La herramienta detecta los caracteres Unicode invisibles más comunes: espacio de ancho cero, uniones y no uniones de ancho cero, BOM, espacios de no separación y otros espacios Unicode, además de caracteres de control.

Understanding Your Results

A zero count is what you want for URL slugs, schema property values, JSON keys, keyword targets, product SKUs, and anywhere else a machine needs to match the string exactly. Small counts (a single BOM at the start of the file, a few non-breaking spaces inside a translated paragraph) are usually harmless in flowing prose but should still be removed from anything a computer will parse. High counts distributed evenly through the text — especially zero-width spaces between every other letter — are a strong indicator that the text has been deliberately obfuscated, either to bypass a plagiarism check, hide an origin, or evade a keyword filter. The Position column tells you exactly where each character sits so you can trace back to its source (a specific paragraph in your CMS, a particular row in your CSV, a broken import).

How to Fix Common Problems

For a one-off cleanup, use the Remove & Clean button and paste the cleaned text back where you found it. If invisibles keep coming back, fix them at the source: check whether your rich-text editor is set to "keep source formatting" on paste (turn it off), whether a translation plugin is inserting formatting marks it doesn't need, whether the file is being saved with a UTF-8 BOM by an editor that adds one by default (most modern editors let you disable this), and whether a CSV import is preserving non-breaking spaces from spreadsheet cells. For code, most editors can show invisible characters via a "render whitespace" or "show invisible characters" setting, and most linters can flag them automatically — turn those on.

SEO Best Practices

Revisa el texto copiado de PDF, Word o páginas web antes de publicarlo o importarlo. Así evitas búsquedas fallidas, problemas de maquetación y datos no válidos.

Example

A product page title that reads "Wireless Headphones" but was pasted from a design brief may contain a zero-width space between "Wireless" and "Headphones" — the tool will report one invisible character at position 8, code point U+200B, name ZERO WIDTH SPACE, count 1. Removing it makes the string identical to what a searcher would type. As a second example, a CSV export from an accounting tool often has a byte-order mark (U+FEFF) at position 0 of the very first cell of the first row, which confuses parsers that don't strip BOMs — cleaning the file once before import fixes the problem for good.

Common Mistakes to Avoid

Un error habitual es dar por limpio un texto solo porque se ve normal: los caracteres invisibles, por definición, no se ven. Ante la duda, comprueba siempre.
