Ideographic Space

The ideographic space is a blank space as wide as one Chinese, Japanese or Korean character, often called a full-width space. It keeps CJK text aligned on a grid. Outside CJK text, people use it to create wider gaps in usernames, bios or layouts where regular spaces get collapsed.

Good to know

Don’t mix it up: It looks like an ordinary space (U+0020) but is much wider and is not treated as ordinary whitespace by every program.

Tip: Paste text into a Unicode inspector to spot stray ideographic spaces, which can break searches and data imports.

Display: the character itself is always the same code point, but its shape comes from the font on the device showing it. If you see an empty box, the font lacks this glyph—the text is still correct.
