Invisible character copier

Four real Unicode characters that render as blank or take up no width, each with one tap to copy and a plain explanation of what it is actually for.

  • Braille pattern blank

    U+2800

    A real, printable braille character that renders as an empty cell. Because it is a printable character rather than whitespace, it can keep a line "alive" in a caption or bio field that automatically strips a line containing only whitespace.

  • Zero width space

    U+200B

    A word-break opportunity with no visible width. Browsers and text layout engines use it to mark where a long run of text without spaces, such as a URL, is allowed to wrap. On its own it adds no visible space.

  • Zero width joiner

    U+200D

    Joins two adjacent code points into a single combined glyph where a font supports it, most visibly in emoji such as a family or profession emoji made of several people joined into one. Outside a sequence a font recognizes, it renders as nothing.

  • Zero width non-joiner

    U+200C

    The opposite of the joiner: it tells a font to keep two adjacent letters from being merged into a connected ligature, which matters in scripts such as Persian and Arabic where letters normally join. It has no visible width of its own.

Paste-test

Paste after copying one of the characters above. This reads only what you paste into this field, in this tab.

What these are actually for

Every character below is a real, documented Unicode code point, not a trick. The braille pattern blank is a printable character that happens to render as empty space, which is why it can survive in a field that strips a whitespace-only line: it is not whitespace to begin with. The zero-width characters take up no width at all and exist for their own documented purpose, such as joining two emoji into one combined glyph. Whether any of them survives how a specific platform processes text is not something we have tested, so this page does not promise a result.

質問

Why would I want an invisible character?

Most often to keep a genuinely blank line inside a caption or bio field that automatically deletes a line made only of ordinary whitespace, or, for the joiner and non-joiner, to control how a font combines the characters next to them.

Will these survive on every platform?

We cannot promise that. No connector on this site has been verified against a live platform yet, and some platforms strip zero-width characters deliberately. Test on the destination before relying on one.

下書きはどこかにアップロードされますか?

いいえ。チェックはあなたのブラウザ内で実行されます。あなたのテキストを運ぶリクエストはなく、何も保存されず、タブを閉じるだけで破棄するのに十分です。

このツールで私の代わりに公開できますか?

まだできません。プロバイダー検証を完了したコネクターはないため、このサイトのどれもまだプラットフォームに公開しません。このページは制限チェックであり、コンポーザーではありません。
