Blank Character — Copy & Paste Empty Characters

What Is a Blank Character?

A blank character is one Unicode code point that appears blank or invisible when pasted. This page is intentionally single-character focused: copy one character, verify its code point, and test whether the target app preserves exactly that one unit.

Use this page when the exact character matters. If you want a longer blank-looking block, use blank text or the invisible text generator. If you want the master taxonomy, start with invisible Unicode characters or the invisible character guide.

Blank Character vs Blank Text

A blank character is a single code point, such as Zero Width Space, Hangul Filler, No-Break Space, or Ideographic Space. Blank text is the visible result after one or more characters are pasted. One blank character can create blank-looking text, but the two ideas are not identical.

When One Blank Character Is Better

• ✦ Use one character when testing whether a username, label, form field, caption, or message box accepts blank-looking Unicode.
• ✦ Use one character when you need a small placeholder and want the Test Box count to stay easy to verify.
• ✦ Use generated blank text only when you need repeated characters or a longer blank-looking block.

Best Blank Character to Try

• ✦ Zero Width Space (U+200B): Use when you want one character with no visible width.
• ✦ Hangul Filler (U+3164): Use when you need a blank-looking character that some fields may preserve.
• ✦ No-Break Space (U+00A0): Use when a visible-width space should stay with nearby text.
• ✦ Ideographic Space (U+3000): Use when a wide blank space is acceptable for layout testing.
• ✦ Em Space or En Space: Use when the goal is visible spacing rather than zero-width text.

How to Copy and Test a Blank Character

• ✦ Choose one character from the grid.
• ✦ Click Copy.
• ✦ Paste it into the Test Box and check the character count.
• ✦ Confirm the code point matches the character you meant to copy.
• ✦ Paste it into your target field.
• ✦ If it appears, disappears, or turns into a box, test another character type.

Practical Examples

• ✦ Single username placeholder: Test one Hangul Filler where a field allows Unicode display-name styling.
• ✦ No-width separator: Test one Zero Width Space between two visible letters to check whether the field preserves hidden separators.
• ✦ Form field debugging: Paste one blank character into a required field, then check whether the app stores, trims, or rejects it.
• ✦ Layout comparison: Compare one No-Break Space with one Ideographic Space to see whether the field treats them as different widths.

Compatibility Notes

One blank character can be handled very differently across apps. Some fields preserve Hangul Filler but remove Zero Width Space. Some forms trim normal-looking whitespace at the beginning or end. Some fonts show unsupported characters as boxes. Always test the exact field after saving or publishing, not only in the editor.

Troubleshooting

• ✦ If the count stays at zero, the character may not have copied or the field may have removed it.
• ✦ If the character shows as a square, the font or app does not render that code point as blank.
• ✦ If the field rejects the character, use visible text or a platform-approved format.
• ✦ If the character works in the Test Box but not elsewhere, the target app is normalizing or trimming Unicode.

Compatibility and Responsible Use

Apps may preserve, remove, normalize, or visually change blank Unicode characters. Use blank characters for formatting, usernames, captions, blank-looking messages, layout testing, and compatibility checking. Follow platform rules and do not use them for spam, impersonation, harassment, evasion, or misleading behavior.
