What Is Hangul Filler?

Hangul Filler (U+3164) is a Unicode character that usually looks like an empty space. Even when you cannot see it, the character is still part of the text you copy or paste. Unicode classifies it as a letter in the Hangul Compatibility Jamo block, not as a regular space.

You might use it to create a blank-looking display name or to add an empty-looking gap without typing a regular space. Some apps allow it, but others remove or reject it. Unlike Zero Width Space (U+200B), U+3164 normally takes up space on screen.

U+3164 vs U+1160 vs U+FFA0

Hangul Filler (U+3164), Hangul Jungseong Filler (U+1160), and Halfwidth Hangul Filler (U+FFA0) are three different characters. They can look similar, but copying one does not give you the others.

To copy Hangul Filler, choose U+3164. The other buttons copy different characters, so use them only if you need U+1160 or U+FFA0.

Character	Unicode	How it differs
Hangul Filler	U+3164	Usually appears blank but still takes up space.
Hangul Jungseong Filler	U+1160	Some apps may change U+3164 into this different character.
Halfwidth Hangul Filler	U+FFA0	A related halfwidth character. Copy it only if you need U+FFA0.

Why Can U+3164 Change to U+1160?

Some apps use a Unicode text-conversion process called NFKC. When that happens, U+3164 and U+FFA0 both change to U+1160. U+1160 itself stays the same. Other apps may simply reject or remove these blank-looking characters instead. The copy and check tools on this page leave your text unchanged.

Character	Original code	After NFKC conversion
Hangul Filler	U+3164	U+1160
Hangul Jungseong Filler	U+1160	U+1160
Halfwidth Hangul Filler	U+FFA0	U+1160

Hangul Filler vs Other Invisible Characters

Hangul Filler often looks blank but still takes up room. Compare it with a normal keyboard space, Zero Width Space (U+200B), and Braille Blank (U+2800) when an app filters one option but keeps another. More single-character options live on the empty character page.

Character	Unicode	Best for	Skip when
Hangul Filler	U+3164	Looks blank but normally takes up space on screen.	When you need a character with no width, or the app does not accept it.
Normal Space	U+0020	Everyday word spacing from the keyboard.	Blank usernames or fields that trim ordinary spaces on save.
Zero Width Space	U+200B	Lets long text wrap without adding a visible space.	When you need a blank-looking character that takes up space.
Braille Pattern Blank	U+2800	Another blank-looking character that may work in names or bios.	When an app does not allow this Braille character.

How to Copy Hangul Filler on iPhone and Android

Open this page in Safari on iPhone or Chrome on Android. Tap Copy Hangul Filler, then paste into the Check Your Copied Hangul Filler box above. When it shows U+3164, try pasting the character into your chosen app.

If the copy button does not work, select the character in the box at the top and copy it manually. An app may still reject blank-looking names after you save them.

Why Doesn't Hangul Filler Work?

The app removes the character

Some apps do not accept blank-looking names or spaces. Try the paste checker above first, then see whether the character remains after saving it in your app.

The pasted character is U+1160 or U+FFA0

Paste the character into the check box above. Some apps may change U+3164 into U+1160 when processing text, while U+FFA0 is a separate character. The checker shows which one you have.

The character looks different on another device

Fonts and apps display blank-looking characters differently. A character that looks empty on one device may show a mark or different spacing on another.

Frequently Asked Questions

What is Hangul Filler (U+3164)?

Hangul Filler (U+3164) is a real Unicode character that often looks blank. Unicode lists it as a letter (category Lo), not as an ordinary space, so it still exists in copied text even when nothing appears on screen.
