Remember

Unicode U+018D
Hex entity ƍ
Decimal ƍ
Named entity (none)
CSS escape \018D
Not the same δ (δ) · &inc; (∆) · ∇ (∇)
Hex, decimal, CSS, and a typed character all produce the same glyph: ƍ. Prefer ƍ when you want an explicit entity.
Using Hex Code: ƍ
Using HTML Code: ƍ
Using CSS Entity: ƍ
Symbol ƍ
How It Works
1. Hex:U+018D → ƍ in HTML. The browser turns it into ƍ.
2. Decimal: same code point as 397 → ƍ. Same result as hex.
3. Named: HTML5 does not define a named entity for this character — use hex or decimal instead.
4. CSS: use \018D in content (not an HTML entity). #point::after appends that ƍ after the paragraph text.
Pitfalls & Tips

Look-alikes
ƍ ≠ δ ≠ ∆

No. HTML5 does not define a named entity for U+018D. Use numeric references like ƍ or ƍ.
Use it in specialized logic or mathematical notation when you need the Latin turned-delta letter, not Greek δ or the increment operator ∆. Prefer numeric entities when encoding must be explicit.
HTML entities (ƍ or ƍ) go in markup. The CSS escape \018D is used in stylesheets (usually in the content property of ::before/::after). Both render ƍ.
δ (U+03B4) is Greek small letter delta. &inc; (U+2206) is the increment operator. U+018D is LATIN SMALL LETTER TURNED DELTA — a different character in Latin Extended-B.
