Blank Text Generator

Four blank-looking characters with different meanings

Unicode does not define a generic character whose only purpose is to make an empty social post or username. Each choice in this generator has a specific encoded identity and function. The Unicode names list for Hangul Compatibility Jamo identifies U+3164 as HANGUL FILLER. The Braille Patterns names list notes that U+2800 often looks like a fixed-width blank but does not act as a space.

The Unicode General Punctuation names list defines U+200B ZERO WIDTH SPACE as an invisible word-separation and line-break control. Unicode’s layout guidance explains that it marks a possible word or line break even though it has no intrinsic width. The same official names list identifies U+2063 INVISIBLE SEPARATOR, also called invisible comma, for separating adjacent items in mathematical notation.

All four code points fall between U+0800 and U+FFFF, so each uses three bytes in UTF-8 under RFC 3629. For example, eight Braille Pattern Blank characters contain exactly 8 Unicode code points and occupy 24 UTF-8 bytes. The tool calculates the byte total with the browser’s UTF-8 encoder, rather than estimating from how wide the result looks.

Blank-looking does not mean interchangeable. A website, editor, search system or messaging app may remove format controls, normalize text, reject unusual characters or display a fallback box. Screen readers and text-processing software can also interpret these code points differently. Test the copied result in its final destination, follow that service’s rules, and do not use invisible text to conceal misleading content. Clipboard access can be denied outside a secure browser context; MDN documents that writeText() can fail with a permission error. The tool then tries the older selection-copy method, which MDN marks as deprecated. If both methods fail, the tool leaves the exact output selected for manual copying.
