Detect Invisible Characters Online
This free invisible character detector scans your text and identifies hidden Unicode characters that cannot be seen normally. Use it as an invisible text detector when copied text, usernames, code, or imported data contains unexpected blank characters.
It is useful when text looks empty but still fails validation, when a username contains hidden separators, or when copied content includes formatting marks from documents, chat apps, editors, and AI tools.

What Invisible Characters Can This Tool Find?
Invisible Unicode Characters
This invisible Unicode character detector identifies formatting code points such as U+200C, U+200D, U+2060, and U+FEFF.
Hidden Formatting Characters
Reveal hidden characters in text that change spacing, joining, line breaks, links, forms, or text checks.
Remove Invisible Characters After Detection
Use the detector as a cleanup workflow: paste the problem text, scan for hidden Unicode code points, review the character names and positions, then copy the cleaned version before publishing, importing, or comparing the text.
- 01
Paste the text that contains suspicious blanks or spacing.
- 02
Run the scan to locate hidden Unicode characters by position.
- 03
Review results such as U+200B, U+200D, U+2060, and U+FEFF.
- 04
Copy the cleaned text after invisible characters are removed.
For related checks, try the empty character guide, compare generated blank text, or test profile text with the invisible name tool.

FAQ
What is an invisible character?
An invisible character is a Unicode character that exists in text but is hard or impossible to see normally. Examples include zero width space, word joiner, BOM, and non breaking space.
How do I detect invisible characters in text?
Paste your text into an invisible character detector and scan it. This page reports hidden Unicode characters with their Unicode value and position in the text.
What is a zero width space?
A zero width space is the invisible Unicode character U+200B. It has no visible width, but it can still affect text processing and line breaking.
Can invisible characters be detected?
Yes. Invisible characters are still real Unicode code points, so software can identify them even when they do not appear visually.
How do I remove hidden Unicode characters?
Scan your text, review the detected characters, then use the cleaned text output with detected invisible characters removed.
What hidden characters can this detector find?
This detector can find common invisible Unicode characters including zero width space, zero width non-joiner, zero width joiner, word joiner, BOM, and non breaking space.
How do I remove zero width spaces from text?
Paste the text into the detector, run the scan, review each U+200B result, then copy the cleaned output after the hidden zero width spaces are removed.
