What Is Hangul Filler?

Hangul Filler (U+3164) is a Hangul Compatibility Jamo character. It often renders as a blank-looking wide glyph, so copied text can look empty while still containing a real Unicode letter.

People reach for it when a form rejects a fully empty value, when a display name should look blank, or when they need empty-looking spacing that is not a keyboard space. It is not the same as Zero Width Space (U+200B), which has no visible width.

If you need a short blank display name rather than a single character reference, open the Invisible Name Generator. To find hidden marks inside pasted text, use the invisible character detector.

U+3164 vs U+1160 vs U+FFA0

Search results for U+3164 sometimes show Hangul Jungseong Filler (U+1160) or Halfwidth Hangul Filler (U+FFA0). Those characters are related in Unicode tables, but they are not interchangeable when you copy and paste.

The main copy button provides U+3164. U+1160 is a different character that some software may substitute for U+3164, while U+FFA0 is its halfwidth form. Use the related-character buttons only when you know you need one of those alternatives.

Character	Unicode	Relation
Hangul Filler	U+3164	A wide Hangul character that often looks blank.
Hangul Jungseong Filler	U+1160	A different character that some software may substitute for U+3164.
Halfwidth Hangul Filler	U+FFA0	The halfwidth form of Hangul Filler. Use it only when U+FFA0 is required.

Hangul Filler vs Other Invisible Characters

Hangul Filler occupies space without a normal visible mark. Compare it with a 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	Blank-looking wide character that still occupies space.	When you need zero width, or when an app rejects Hangul Compatibility Jamo.
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	Invisible break points with no visible gap.	When you need a blank that still looks like empty spacing on screen.
Braille Pattern Blank	U+2800	Another blank-looking spacing character used in names and bios.	When a platform filters Braille patterns specifically.

How to Copy Hangul Filler on iPhone and Android

On iPhone Safari or Android Chrome, open this page, tap Copy Hangul Filler, then paste into Notes or the Test box on this page first. Once the checker reports one U+3164, paste into the app field you want to try.

If clipboard access is blocked, long-press inside the character preview, select the blank glyph between the brackets carefully, and copy manually. Platform name fields still decide whether the character sticks after save.

Frequently Asked Questions

What is Hangul Filler (U+3164)?

Hangul Filler is a Unicode character in the Hangul Compatibility Jamo block. It belongs to the Other Letter (Lo) category, looks blank on many screens, and still counts as real text when you copy and paste it.

How do I copy Hangul Filler?

Tap Copy Hangul Filler near the top of this page, then paste into the Test Your Copied Hangul Filler box further down to confirm you got U+3164. On iPhone and Android, use the same copy button in Safari or Chrome, then paste into the field you want to try.

Is U+3164 the same as a normal space?

No. A normal space is U+0020. Hangul Filler is an Other Letter (Lo), not a space character, so many apps treat it differently from keyboard spaces.

Can I use Hangul Filler for an invisible name?

Sometimes. Display-name fields may keep a blank-looking Hangul Filler, but usernames and platform filters vary. For short blank-name presets, use the Invisible Name Generator instead of building names only on this page.

What is the difference between U+3164 and U+1160?

They are different characters. U+3164 is Hangul Filler, while U+1160 is Hangul Jungseong Filler. Some software may convert U+3164 to U+1160 while processing text, so the character you paste can sometimes change.

Why does Hangul Filler not work after pasting?

Some apps strip, rewrite, or refuse blank-looking characters. Others may normalize U+3164 toward U+1160, or a font may render the filler differently. If one app rejects it, try another field or compare with Zero Width Space and Braille Pattern Blank.
