🧠 How It Works
Hexadecimal Code
̰ uses the Unicode hexadecimal value 0330. Place it immediately after a base character, e.g. a̰.
Decimal HTML Code
̰ uses the decimal Unicode value 816 for the same combining mark.
CSS Entity
\0330 is used in CSS stylesheets in the content property of pseudo-elements, following a base character in the element text.
Combined result
All three methods attach a tilde below the base letter: a̰. Unicode U+0330 is a combining character—it never displays meaningfully on its own.

Don’t
- Use ̰ alone without a base character
- Confuse ̰ (combining) with ∼ (Tilde Operator) or ~ (U+007E)

\0330directly in HTML text nodes - Expect a named HTML entity for U+0330
- Use HTML entities in JS (use
\u0330instead)
