About Blank Space Copy
Blank Space Copy is a focused browser tool for preparing blank-looking Unicode characters, checking what was copied and understanding why the same text behaves differently across apps.

What this site does
The homepage creates an exact sequence from one of four documented characters. Its checker counts and identifies a focused set of blank, spacing and format characters without changing the input. The guide explains how the available characters differ, and the help page diagnoses copy, paste, save and display failures.
The product is designed around a short task: prepare text, use it in another field, then verify what happened. It does not promise that another app will accept or display a character.
Who operates it
Blank Space Copy is the operating name used for this independent website. It is not affiliated with Unicode, a browser vendor, a messaging platform, a game or a social network.
The site does not require an account. Product questions, correction reports and privacy requests go to the contact address below.
Choose the tool for the change you need
| Task | Tool and output |
|---|---|
| Prepare & copy | Blank Space Copier Choose a blank-looking character and quantity, copy exact text, then verify a paste. |
| Inspect | Invisible Character Checker Names, counts and original positions; leaves input unchanged. |
| Remove | Invisible Character Remover Choose character types and individual positions; review kept/removed output. |
| Normalize | Whitespace Normalizer Choose spacing rules; compare preserved and converted special spaces. |
| Join | Remove Line Breaks Join wrapped lines with a separator; optionally preserve blank-line paragraphs. |
| Format gaps | Instagram Line Breaks Keep real newlines; optionally place Braille blanks or periods on internal gap lines. |
Two examples you can reproduce
Keep two paragraphs
Alpha beta Gamma delta
Choose “Keep blank-line paragraphs” and one space in Remove Line Breaks. Result:
Alpha beta Gamma delta
Two LF boundaries remain between the paragraphs; two wrapped boundaries are joined.
Open line joinerHow information and tools are checked
Character names, code points, general categories and White_Space classifications come from the Unicode Character Database. The site distinguishes everyday descriptions of width and appearance from formal Unicode properties.
- Fixed examples test the exact output for U+3164, U+2800, U+200B and U+00A0.
- Counts use Unicode code points, which are not always the same as visible letters, emoji or cursor positions.
- Clipboard success appears only after the browser reports a successful write. A manual selection route remains available.
- The checker names the directory’s special spaces, blank-looking characters and format controls. It lists each occurrence at its original one-based code-point position and summarizes repeated types. Ordinary spaces, tabs and line breaks are counted separately; “View every code point” includes the remaining text. Checking does not remove or normalize the input, and editing it clears the old report.
- The normalizer compares the same rules with special spaces preserved or explicitly converted. Its record follows original code-point positions through each processing step. The remover supports type choices and individual position choices; its record includes kept and removed characters with output positions. Editing the original clears old results and position choices. TXT downloads use UTF-8 without adding a byte-order mark.
- Character references compare manually pasted text with the exact prepared sequence. Font demonstrations measure rendered text with DOM Range, including any system-font fallback. Their controls change local examples; they do not normalize the prepared output or determine what another app saved.
- Browser testing checks the main task flow and responsive layout; target-app behavior must be tested in that app.
What the site can and cannot verify
A result on this site can confirm the prepared code points, their count and whether the focused checker finds them. It cannot control clipboard permissions, fonts, trimming, normalization, validation or account rules in another app.
“No characters from the named set” means the checker found none from its documented set. It is not a security scan, content-authenticity test or exhaustive Unicode analysis.
