Using HTML Code: Ƴ
Using CSS Entity: Ƴ
Typed directly: Ƴ
Not Y (plain capital Y)
How It Works
1. Hex:U+01B3 → Ƴ in HTML. The browser turns it into Ƴ.
2. Decimal: same code point as 435 → Ƴ. Same result as hex.
3. CSS: use \01B3 in content (not an HTML entity). #point::after appends that Ƴ after the paragraph text.
4. Typed / compare: paste Ƴ in UTF-8. Keep plain Y (U+0059) as a different letter.
5. No named entity: HTML5 does not define a name for U+01B3 — use numeric references or type the character.

Named?
No named entity

vs Y
Not plain capital Y
Keyboard Y is U+0059. Use U+01B3 only when you need the hooked form.
Pair
Lowercase is U+01B4
Small letter ƴ has no named entity either — use ƴ or ƴ.
vs Ÿ
Not diaeresis Ÿ
Ÿ (U+0178, Ÿ) has two dots. Ƴ has a hook on the stem.
CSS vs HTML
Do not mix escapes
\01B3 belongs in CSS strings. Ƴ / Ƴ belong in HTML.
