About the Invisible Character tool
An invisible character looks like nothing — but the computer sees a real character. People use one to make a blank name in a game, to send an empty message, or to add empty lines to a bio where normal spaces get removed.
This page has the 13 most useful blank and zero-width characters. Press Copy next to one, then paste it where you need it. You can copy many at once for a longer blank.
The second part does the opposite: paste any text and the tester shows every hidden character in it — and can clean them out.
Everything happens in your browser. Nothing is uploaded.
Features
- 13 invisible characters with what each one is good for and where it works
- One-click copy, one character or up to 500 at once
- A width preview — each card shows how wide the character is between two letters
- Hidden character tester — names, codes, how many, and where in the text
- Clean the text — remove zero-width characters and turn odd spaces into normal ones
- Emoji stay whole — joiners inside emoji like 👩💻 are kept when you clean

Blank names and empty messages
Most apps and games trim normal spaces, so a name of only spaces is refused. The Hangul filler (U+3164) and the braille blank (U+2800) are letters as far as the app knows, so they often pass.
Be honest with yourself about the limits:
- Some apps remove them or show a box □ instead. Each app decides for itself, and it can change with an update.
- Some games block blank names on purpose. If one character does not work, try the next one, or put a dot or a real letter next to it.
- Do not use them to trick people — for example a blank sender name to look like someone else. That breaks most apps' rules.
Finding hidden characters
Text copied from a web page, a PDF, an AI chat or a messaging app can carry characters you cannot see. They cause real problems: a password that "does not match", a search that finds nothing, a spreadsheet cell that will not add up, code that will not run.
Paste the text into the tester. It lists each hidden character with its name, its code, how many times it appears and where the first one is. The text below shows a yellow tag at each place. Press Remove them to get a clean copy: zero-width and format characters are taken out, and special spaces become normal spaces.
Frequently asked questions
How do I copy an invisible character?
Press the Copy button next to the character you want, then paste it (Ctrl+V, or long-press and Paste on a phone). To copy several in a row, change *How many to copy at once* first.
Which invisible character works best for a blank name?
Try the Hangul filler (U+3164) first, then the braille blank (U+2800), then the Hangul choseong filler (U+115F). Games change their rules, so there is no character that works everywhere.
What is a zero width space?
A character with no width at all (U+200B). It tells the browser where a long word may break. People also use it to stop a word from turning into a link or a tag. Many apps remove it.
Is an invisible character the same as a space?
No. A normal space is U+0020, and apps often remove extra spaces. An invisible character is a different character that only looks empty, so it is usually kept.
Why does my text have strange characters in it?
Copying from websites, PDFs and chats can add no-break spaces, zero-width spaces or a byte order mark. Paste the text into the tester to see them, then press Remove them.
