Copy a character that looks like blank space
Choose a Unicode blank character, copy it with one click, and test it before using it elsewhere.
Recommended first
Hangul Filler
A commonly used blank-looking Unicode character. Try this option first when an ordinary keyboard space is rejected.

Ideographic Space
A full-width Unicode space used in East Asian typography. It can work when a platform filters the first method.

Confirm that the character was inserted
The field can look empty even when it contains a character. Use the character count to confirm it is present.

Practical guide
What invisible text is and when it can be useful
An invisible character is a real Unicode character that occupies a position in text while displaying as empty space. It is different from deleting the text, and it is not always the same as pressing the spacebar. Computers store letters, punctuation, symbols, and spacing characters as code points. Some of those code points have no visible mark, which means a field can contain data even though it appears blank to the reader.
This can be useful when a website or application removes ordinary spaces but still accepts other Unicode characters. For example, someone may want to separate parts of a display name, create breathing room in a short profile, test how a form validates unusual input, or reproduce a spacing problem while troubleshooting software. Designers and developers may also use blank-looking characters to check truncation, copy-and-paste behavior, font fallback, character counting, and accessibility handling across browsers or devices.
How to use the invisible character copier
- Start with Hangul Filler. Select “Copy character” under Method 1. Your clipboard will contain one U+3164 character even though you cannot see it.
- Test before publishing. Paste it into the tester on this page, or choose “Insert in tester.” The counter should change from zero to one.
- Paste it into the destination. Open the username, message, layout, or test field where you need it and use the normal paste command for your device.
- Try the alternative if necessary. If the destination removes U+3164, copy the U+3000 Ideographic Space and test again.
- Verify the saved result. Some services accept a character while editing but remove or normalize it after submission.
Why two blank-character methods are provided
Platforms do not process Unicode in exactly the same way. One service may preserve Hangul Filler, another may replace it, and a third may reject it completely. Ideographic Space is wider and behaves more like a typographic full-width space, so it provides a useful alternative. Neither method is guaranteed: applications can update their filters, normalize text, collapse spacing, or prohibit invisible characters to reduce spam and misleading names.
Use invisible text responsibly
Invisible characters should improve formatting or support legitimate testing, not impersonate another person, conceal harmful links, evade moderation, or mislead readers. They can also create accessibility problems because screen readers and other assistive tools may announce, pause at, or ignore them unpredictably. Avoid using them in passwords, email addresses, legal names, payment information, source code identifiers, or any data where exact matching matters.
If the destination supports normal spacing, line breaks, margins, or formatting controls, those are usually the better choice. Use this tool when you specifically need to copy and test a Unicode blank character, and always check the final result on the platform where it will appear.
