U+3164 Hangul Filler Copy & Paste
Copy the real Hangul Filler, see why it can look blank while still counting as a letter, and compare it with other empty-looking Unicode characters.

SEE IT IN PRACTICE
Separate a display problem from a changed value.
Copying successfully confirms the clipboard step. To check the destination, save, reopen the field, copy its contents and inspect them in the checker.
- Still U+3164: the code point survived. If a box or mark appears, investigate the destination’s font and display behavior.
- A different code point: the stored value changed. For example, the Unicode name list records a compatibility mapping from U+3164 to U+1160; this does not mean every app applies it.
- An empty input: no character was recovered. Check whether saving succeeded and whether the field permits that value.
A required field can still reject a blank-looking letter. Use a valid visible value when the field requires one. For a box or replacement symbol, follow the display troubleshooting steps. Sources: Hangul Compatibility Jamo name list and Unicode display guidance.

COMPARE THE COMMON CHOICES
U+3164, U+2800 and U+200B are not interchangeable.
| Character | Unicode category | Typical width | Main reason to choose it |
|---|---|---|---|
| Hangul Filler | Lo · Other Letter | Blank-looking width in many fonts | You want a letter-like code point that can appear blank |
| Braille Pattern Blank | So · Other Symbol | Blank Braille cell | You want a symbol with a blank cell appearance |
| Zero Width Space | Cf · Format | Zero | You want an invisible break opportunity, not a gap |
| No-Break Space | Zs · Space Separator | Ordinary space-like gap | You want spacing that resists line breaking |
WHEN IT WORKS — AND WHEN IT DOESN’T
Treat U+3164 as a character to test, not a platform bypass.
Blank-looking labels
Some fields and fonts render U+3164 as an empty-looking position. It can still count toward character limits and validation.
Font fallback
If a font lacks the expected glyph behavior, the character may show a box, a mark or different spacing.
Normalization and filtering
An application can normalize, remove or reject U+3164. A successful copy does not guarantee a successful save.
Verify after saving
Reopen the destination and use the checker if you need to confirm the code point survived.
ONE CHARACTER, SEVERAL SEARCHES
Hangul Filler, U+3164, U 3164 and Unicode 3164 mean the same code point here.
These are different ways to name the same character. Copy buttons on this page insert the actual character; typing “U+3164” inserts its visible name instead.
Need to remove it from existing text?
Analyze the text in the invisible character remover, select U+3164 explicitly, and compare the cleaned output before copying.
SOURCE & TEST BOUNDARY
Unicode identity does not guarantee a blank appearance everywhere.
The name, block, category and White_Space statement use Unicode Character Database 18.0.0. The three-font display is a controlled page example; font fallback and application filtering remain destination-specific.
THREE STEPS
Copy U+3164, place it, then confirm the save.
- Copy the character itself.
Copy 1 for a single blank-looking position, or a short repeated sequence when the destination needs a wider gap. The manual copy field holds the same U+3164 when the clipboard button is unavailable.
- Paste it where the blank should appear.
Typical places are a display name, a label, a caption line or a field that must not be empty. The outlines and brackets on this page are an explanation layer and are never copied.
- Reopen the destination and check what was stored.
Apps can normalize, filter or reject this code point. If the result matters, paste the saved value into the checker instead of trusting the first paste.
IN PRACTICE
Why people copy Hangul Filler rather than a space.
A blank-looking name or label
In many fonts U+3164 occupies a position without painting a visible glyph, which is why it is popular for empty display names and category labels. Whether a specific platform accepts it is a separate question.
Spacing where a space is not allowed
Some fields strip spaces at the beginning or end of a value. A character that is not a space can survive that trim, although validation rules may still reject it.
Keeping a required field non-empty
A blank-looking letter is not an empty string, but that does not make it a valid required-field value. Follow the field’s rules and enter visible content when required.
A layout gap that should survive a leading trim
Leading whitespace is often removed automatically. A width-bearing non-space character is one way to hold a visible position, at the cost of adding a real code point.
Understanding a character someone else used
When text behaves as though a blank is present, U+3164 is one of the usual explanations next to U+2800 and U+200B.
QUESTIONS
Hangul Filler FAQ
Is U+3164 really invisible?
It is a blank-looking character in many fonts rather than a formally invisible one. Its Unicode category is Lo, Other Letter, and it is not marked as whitespace. Rendering depends on the font, the operating system and the app.
Is U+3164 the same as a space?
No. A space is a separator with White_Space set to Yes. U+3164 is a letter with White_Space set to No, so it can be treated differently by text trimming, word counting, search and validation.
Why does it sometimes appear as a box or a mark?
First inspect the saved text. If it still contains U+3164, missing font support or display behavior may explain the mark. If it contains a different code point, the value changed; a font change alone will not restore the original.
Should I use U+3164 or U+2800 Braille Pattern Blank?
Both look blank in typical fonts and both carry width, but they are different Unicode classes: a Hangul letter versus a Braille symbol. Test the specific destination, because a platform can normalize one and keep the other.
Will a blank nickname made with U+3164 be accepted?
That cannot be promised from this page. Platforms validate names in their own way and change those rules over time. Copy, save and then verify the stored value before relying on it.
Does U+3164 count toward character limits?
Yes. It is one code point, so most counters include it even when nothing visible appears. A repeated sequence also multiplies the count as well as the width.
How do I remove U+3164 from text I already have?
Analyze the text in the invisible character remover, select U+3164 explicitly, and compare the cleaned output before copying it anywhere.
How many should I copy for a wider gap?
One code point creates one position. Repeating it widens the blank in most fonts, but the exact width is font-dependent, so a two-character gap on one device may look different on another.
