Meaning & usage
A space is not just a space: Unicode has a whole drawer of them. The no-break space (U+00A0) glues words together; en and em spaces (U+2002/2003) come from type widths; the zero-width space (U+200B) is invisible and used for 'blank' usernames and line-break hints; the braille blank (U+2800) looks empty but counts as a character, which is why it stars in blank-name tricks. The main glyph here, ␣, is the visible symbol for a space used in keyboards and proofreading.
Examples in use
- Blank display name: copy U+2800 from the grid
- 10 km with a no-break space never splits
- ␣ marks a space in keyboard diagrams

Frequently asked questions
Which space makes a 'blank' name?
The braille pattern blank (U+2800) is the usual choice: it renders as nothing but registers as a character. Some apps strip it; the zero-width space (U+200B) is the fallback.
Why does my copied space disappear in HTML?
Browsers collapse ordinary spaces. Use the no-break space (U+00A0, HTML ) where a visible gap must survive.
Why does ␣ sometimes show as a box or question mark?
The box (called tofu) means the device or font viewing it has no drawing for U+2423 (Open Box). The character itself is fine — try a different font or a newer device, or use one of the variants on this page.
Is the Space Symbols (Invisible & Blank Spaces) free to use?
Yes. ␣ is a standard Unicode text character published in the Unicode Character Database. You may use it in personal and commercial documents, designs and products without permission or payment.
