Where hidden characters come from
Zero-width spaces are added by some websites and editors to allow line breaks in long words or URLs. Word processors insert no-break spaces after short words in French and before units. A byte-order mark (U+FEFF) often sits at the very start of files saved by Windows tools. None of these show on screen, but all of them change character counts and can stop a search or a password from matching.
The Unicode Standard lists these as "default ignorable" or space characters. The detector checks for the common ones, including directional marks that can make text display in a different order than it is stored.
Questions
What is an invisible character?
A Unicode character that takes up space but shows nothing, like the Hangul Filler (U+3164) or Braille Pattern Blank (U+2800), or one that has no width at all, like the zero-width space (U+200B). Apps that reject an empty field often accept them.
Which invisible character works for a blank name?
The Hangul Filler (U+3164) is the one most often accepted for blank names in games and apps. If a platform strips it, try the Braille Pattern Blank (U+2800). Platforms change their rules, so test before relying on one.
How do I copy and paste a blank space?
Press Copy next to a character in the list, then paste where you need it. The button copies exactly one character; press it again or paste several times for more.
Why would text contain hidden characters?
Copying from PDFs, web pages, chat apps and AI tools can carry zero-width spaces, joiners, byte-order marks and non-breaking spaces. They can make two identical-looking words fail to match, break code or URLs, and change character counts.
Can invisible characters be used to watermark or track text?
They can: some systems hide patterns of zero-width characters in text. The detector here lists every one it finds with its code point, so you can see and remove them.
