U+2800 vs U+200B vs U+3164: Which Invisible Character Should You Use?
Not all invisible characters are the same. If you have ever pasted a blank character into WhatsApp and had it vanish, or used one in a game name only for it to show as a box, the character you picked was the problem. This guide compares the three most popular invisible Unicode characters — U+2800, U+200B and U+3164 — and tells you exactly which one to use on WhatsApp, Discord, Instagram and in games like Free Fire.
The short answer: U+2800 (Braille Pattern Blank) is the best all-rounder for messages. U+3164 (Hangul Filler) is the best for blank game names and nicknames. U+200B (Zero-Width Space) is a specialist tool that is powerful but unreliable across apps. Details below.
The Three Invisible Characters at a Glance
| Character | Code Point | Unicode Name | What It Looks Like |
|---|---|---|---|
| ⠀ | U+2800 | Braille Pattern Blank | Occupies a full character width, renders as blank |
| | U+200B | Zero-Width Space | Literally zero width — truly invisible even in selections |
| ㅤ | U+3164 | Hangul Filler | Full-width blank, behaves like a letter with no glyph |
You can copy any of these from our invisible text generator — the homepage tool generates all three, and each tool page on the site lets you pick the character you need.
U+2800 (Braille Pattern Blank): The Best All-Rounder
U+2800 is the invisible character we recommend for most people. It is technically a Braille cell with no dots raised, which means every text engine on the planet treats it as a real character while rendering nothing visible.
Why it wins for messages: WhatsApp, Instagram and Messenger all trim plain spaces, but they accept U+2800 as genuine content. A single U+2800 is enough to send a blank message that arrives as an empty bubble. It also survives copy-paste through most apps without being stripped.
Where it struggles: Some games and older apps reject Braille characters, and a few chat filters flag repeated Braille blanks as spam. In those cases, U+3164 is the better pick.
Best for: blank WhatsApp messages, blank Instagram bio lines, empty status text, invisible Discord messages.
U+200B (Zero-Width Space): The Invisible Specialist
U+200B is the sneakiest of the three. It has zero width, so it does not even occupy space — it is completely invisible, even when you select the text. Its original purpose was to suggest a line-break opportunity in long words, which is why it behaves oddly in some apps.
Why people use it: Because it is truly invisible, it is perfect for hiding text inside other text, breaking up words to dodge simple word filters, and creating “empty” strings in apps that measure message length. It is also the character of choice for anyone experimenting with hidden messages in plain sight.
Why it is unreliable: Many apps strip zero-width characters automatically — WhatsApp sometimes eats them, and several games reject them outright. Because it has no width, pasting it can also behave strangely in input fields, making it hard to tell whether you copied anything at all.
Best for: steganography-style tricks, splitting words to bypass basic filters, zero-width watermarks in text.
U+3164 (Hangul Filler): The Gaming Champion
U+3164 comes from the Korean Hangul script, where it acts as a placeholder in syllable blocks. Rendering engines treat it as a full letter that simply has no visible shape, which makes it incredibly reliable in places that reject the other two.
Why gamers love it: Free Fire, PUBG Mobile, Mobile Legends and most other games accept U+3164 in player names where U+2800 gets rejected or shows as a box. It is the standard trick behind every blank Free Fire name you have ever seen. Our Free Fire invisible space tool generates exactly this character for blank nicknames.
Where it works beyond games: U+3164 also makes excellent blank Discord nicknames, invisible channel names, and empty Instagram usernames in bios. Because it behaves like a regular letter, it rarely gets stripped.
Best for: blank game names (Free Fire, PUBG, COD Mobile), invisible Discord nicknames, any app that rejects Braille blanks.
Head-to-Head: Which Character for Which App?
| Use Case | U+2800 | U+200B | U+3164 |
|---|---|---|---|
| WhatsApp blank message | Best | Unreliable | Works |
| Instagram bio spacing | Best | Works | Works |
| Free Fire blank name | Often rejected | Rejected | Best |
| Discord blank nickname | Works | Works | Best |
| Discord blank message | Best | Works | Works |
| Hiding text in text | Visible gap | Best | Visible gap |
| Empty status / About line | Best | Unreliable | Works |
When in doubt, start with U+2800 — if the app rejects it, switch to U+3164. Keep U+200B for the specialist tricks it is genuinely best at.
How to Test Before You Commit
Never paste an invisible character into your real game name or public profile without testing first. Here is the safe routine:
- Copy from a proper generator. Use our invisible text generator or the Unicode text converter so you know exactly which character you are getting.
- Test in a private chat. Send it to yourself or a test account in the target app and see whether it survives.
- Try two or three copies. Some apps trim a single invisible character but accept two or three. Our generator lets you set the repeat count.
- Check on a second device. A character that looks blank on your phone might render as a box on an older device. If your audience uses old phones, prefer U+2800 or U+3164 over U+200B.
Common Mistakes to Avoid
- Copying plain spaces. Regular spaces (U+0020) get trimmed by almost every app. If your blank message will not send, you probably copied spaces, not an invisible character.
- Using U+200B in game names. Games almost universally strip zero-width characters. Use U+3164 for blank names instead.
- Mixing characters randomly. Each app has a favorite. Pick the right one from the table above instead of pasting all three and hoping.
- Forgetting the fallback. If a trick stops working after an app update, the other two characters usually still work — app patches rarely block all three at once.
The Bottom Line
U+2800 is your everyday invisible character for messages and bios, U+3164 is your gaming and nickname specialist, and U+200B is the stealth tool for hiding text inside text. Now you know exactly which one to reach for — grab any of them free on our homepage and test the difference yourself.
