Integral Extension Symbol
⎮ (U+23AE) is the Integral Extension character used as part of larger integral-like notation in technical systems.
U+23AE
⎮ is a Unicode character named INTEGRAL EXTENSION (U+23AE). It’s mainly used in technical or typesetting contexts where integral-style symbols are built from components. You can copy it directly or reference it by its Unicode code point.
Integral Extension Symbol Meaning
⎮ (Unicode U+23AE, “INTEGRAL EXTENSION”) is a technical character intended to help construct integral-style notation that can extend to match surrounding content. In typography and math rendering, “extension” glyphs are often used as building blocks so the visual height can adapt (for example, alongside integral signs or related operator layouts). Outside of mathematical typesetting, it has no widely established everyday meaning. If you’re writing plain text, it may look unusual depending on the font; in math-capable fonts and Unicode-aware systems it’s more likely to render as intended.
Common uses
- •Building multi-part integral or operator notation in custom math layouts
- •Typesetting in markup systems that support Unicode technical symbols
- •Adding consistent operator glyphs in documentation and technical writing
- •Designing mathematical UI components where symbol stretching is needed
- •Copy/paste usage in editors that require exact Unicode characters

FAQ
What does ⎮ mean?
⎮ is the Unicode character “INTEGRAL EXTENSION” (U+23AE). It’s primarily a typesetting/typography building block for integral-like notation that can extend to fit.
How do I copy ⎮ into my document?
You can copy the character directly (⎮). It’s also available via its Unicode code point U+23AE, or via the HTML entity ⎮.
Will ⎮ render correctly in all fonts?
Not necessarily. Because it’s a technical Unicode symbol, appearance depends on whether your font supports U+23AE. Math-capable Unicode fonts usually do better.
Is ⎮ the same as a regular vertical bar |?
No. While it may look similar to a vertical line in some fonts, ⎮ is specifically U+23AE (“INTEGRAL EXTENSION”) and is intended for technical/operator notation.
