Combining minus sign below is Unicode U+0320 (COMBINING MINUS SIGN BELOW. It is a non-spacing mark placed immediately after a base letter to add a short minus-like bar under it — often in phonetics and linguistics.
Remember
Character ◌̠ (under base letter)
Unicode U+0320
Hex entity ̠
Decimal ̠
CSS escape \0320
Named entity (none)
Hex, decimal, and CSS all produce the same combining mark. Write it right after the base letter (a̠ → a̠).
Using Hex Code: x̠
Using HTML Code: a̠
z̠ (CSS mark on z)
Compare: math − vs diacritic a̠
How It Works
1. Hex:U+0320 → ̠ right after x. The browser combines them into x̠.
2. Decimal: same code point as 800 → ̠ after a. Same combining mark.
3. CSS: use \0320 in content (not an HTML entity). #point::after appends the mark after z, producing z̠.
4. Compare:− is a spacing math operator; ̠ is a diacritic under a letter.
Pitfalls & Tips
Common mistakes when working with combining minus sign below.
Order
Base letter first
Write a̠, not ̠a. The mark attaches to the preceding character.
Named?
No named entity
HTML5 does not define a named entity for U+0320. Use numeric forms.
vs −
Not mathematical minus
Use − for equations. This character is only a combining diacritic.
Underline
Not for UI underlines
Use CSS text-decoration for UI underlines — not combining diacritics.
CSS vs HTML
Do not mix escapes
\0320 belongs in CSS. ̠ / ̠ belong in HTML.
Semicolon
End references
Always finish with ; — write ̠, not ̠.
