How It Works
1. Named:ŷ is the HTML5 named entity for U+0177. Clearest form in HTML source.
2. Hex:U+0177 → ŷ in HTML. Same glyph as named.
3. Decimal: same code point as 375 → ŷ. Same result.
4. CSS: use \0177 in content (not an HTML entity). #point::after appends that ŷ after the paragraph text.
Pitfalls & Tips
Common mistakes when working with the y circumflex entity.
Named
Prefer ŷ
HTML5 defines a named entity for this letter — use it for readable HTML.
CSS vs HTML
Do not mix escapes
\0177 belongs in CSS. ŷ / ŷ / ŷ belong in HTML.
Look-alikes
Not y or ý
Plain y is U+0079; y acute is U+00FD. Circumflex is a different diacritic.
Case
ŷ vs Ŷ
Uppercase is U+0176 (Ŷ) — a different code point from U+0177.
Semicolon
End references
Always finish with ; — write ŷ, not &ycirc.
UTF-8
Declare charset
If you paste ŷ directly, serve the page as UTF-8 with <meta charset="UTF-8">.
