How It Works
1. Hex:U+01A7 → Ƨ in HTML. The browser turns it into the glyph.
2. Decimal: same code point as 423 → Ƨ. Same result as hex.
3. CSS: use \01A7 in content (not an HTML entity). #point::after appends that glyph after the paragraph text.
4. Compare: plain S, uppercase tone two Ƨ, and lowercase tone two ƨ are three different characters.
