Starts with the Hangul Filler (U+3164), the character most often used for blank nicknames in games and messengers that accept Korean letters. Its dots show where people usually report success. If a name field rejects it, try the Halfwidth Hangul Filler or two characters combined.
How to use
- Tap a character in the list to copy it. The bars around each preview show how wide it is in your font.
- The dots under each name sum up what people usually report on each platform: green often works, yellow is mixed, an empty circle means it is usually removed or rejected.
- Need several? Under Blank text, pick a character and a number, then tap the result to copy them all.
- Instagram line breaks: write your caption, then copy it. Empty lines get an invisible Braille blank so they stay.
- Paste anything into the last box to see how many characters it has and where the hidden ones are.
- Apps and games change their name rules often, and some ban blank names outright. Try a character in a test post or name first and follow each service’s rules.
- Zero-width characters can break search, links and passwords. Don’t use them where text must match exactly.
- Nothing you paste leaves your device.
Why there are so many blank characters
Unicode has dozens of characters that print nothing. Ordinary spaces are often trimmed or collapsed by apps, and many name fields reject them, so people use characters that look empty but count as letters or symbols. The Hangul Filler (U+3164) is officially a Korean letter with no shape, which is why games and messengers that accept Korean often accept it in names. The Braille Pattern Blank (U+2800) is a Braille cell with no dots, treated as a visible symbol, which keeps empty lines alive in captions. Zero-width characters such as U+200B take no space at all.
Each entry shows its width in your font and dots summarizing how it usually fares on common platforms: green often works, yellow is mixed, an empty circle means it is usually removed or rejected.
Use with care
Platforms change their name rules, and some ban blank names outright, so try a character on a test post or name first and follow each service’s terms. Zero-width characters can break search, links, passwords and spreadsheet lookups, because two strings that look identical no longer match. The checker box shows every hidden character in pasted text, which helps when a copied password or code mysteriously fails.
Frequently asked questions
How do I make a blank or invisible name?
Copy the Hangul Filler or another blank marked green for your platform and paste it into the name field. If the field rejects it, try another character or combine two.
How do I add line breaks in an Instagram caption?
Write the caption under Instagram line breaks and copy it. Empty lines get a Braille blank, so they stay when you post instead of being removed.
What is the difference between a space and an invisible character?
A normal space (U+0020) is often trimmed or collapsed. Invisible characters are different code points that apps usually treat as content, so they are kept.
How do I find hidden characters in text?
Paste the text into the last box. It counts the characters and marks every invisible one with its name and position.
Is copying blank characters allowed?
Copying is harmless, but some games and apps forbid blank names. Check the rules of the service before using one.
