Lowercase o with tilde and macron (ȭ) is the Unicode character at U+022D in Latin Extended-B. Official name: LATIN SMALL LETTER O WITH TILDE AND MACRON — the letter o with both a tilde and a macron above.

Prefer ȭ or ȭ in HTML when you need an entity. You can also type ȭ in a UTF-8 document.

How It Works
1. Hex:U+022D → ȭ in HTML. The browser turns it into ȭ.
2. Decimal: same code point as 557 → ȭ. Same result as hex.
3. CSS: use \022D in content (not an HTML entity). #point::after appends ȭ.
4. Typed: paste ȭ in a UTF-8 document for linguistic or phonetic text. There is no named entity — numeric form is required when you need an entity.
Pitfalls & Tips
Common mistakes when working with lowercase o with tilde and macron.
Named?
No named entity
HTML5 does not define a named entity for U+022D. Use ȭ or ȭ.
õ
Not tilde alone
õ (õ) has only the tilde. ȭ also has a macron — different letter, different code point.
ō
Not ō alone
ō (ō) is o with macron only. Do not swap it for ȭ when both marks are required.
Fonts
Need Extended-B coverage
Some fonts omit Latin Extended-B. Prefer a font that includes U+022D for reliable glyphs.
CSS
Pad the CSS escape
Prefer \022D (four hex digits). A short \22D can swallow the next hex digit if one follows immediately.
CSS vs HTML
Do not mix escapes
\022D belongs in CSS strings. ȭ / ȭ belong in HTML.
Semicolon
End references
Always finish entities with ; — write ȭ, not ȭ.
Compatibility
Browser Support
Lowercase o with tilde and macron (U+022D) and its entity forms (ȭ, ȭ, CSS \\022D) are supported in all mainstream browsers. Visible glyphs depend on Latin Extended-B font coverage.

Bottom line: Prefer ȭ or ȭ in HTML when encoding must be explicit, and \\022D only inside CSS content. There is no named entity.
Remember
Key Takeaways
Unicode: lowercase o with tilde and macron is U+022D (decimal 557) — glyph ȭ.
HTML: use ȭ or ȭ — no named entity.
CSS: use \022D inside content for generated text.
Watch out: ȭ ≠ õ ≠ ō ≠ plain o.
One line:U+022D → ȭ / ȭ / CSS \022D (no named entity).
Frequently Asked Questions
Use ȭ (hex), ȭ (decimal), type ȭ in UTF-8, or the CSS escape \022D in content. There is no HTML5 named entity for U+022D.
U+022D (LATIN SMALL LETTER O WITH TILDE AND MACRON). Hex 22D, decimal 557. It belongs to Latin Extended-B (U+0180–U+024F).
No. HTML5 does not define a named entity for this character. Use numeric references like ȭ or ȭ when you need an entity form.
Use it for linguistic and phonetic notation that needs ȭ. Prefer õ when only the tilde is required, and ō when only the macron is required.
HTML entities (ȭ or ȭ) go in markup. The CSS escape \022D goes in stylesheet strings (usually content on ::before/::after).
No. õ (U+00F5, õ) has only a tilde. ō (U+014D, ō) has only a macron. U+022D is a precomposed letter with both marks.
