Lowercase u with diaeresis and acute (ǘ) is the Latin Extended-B character at Unicode U+01D8 (LATIN SMALL LETTER U WITH DIAERESIS AND ACUTE). It stacks two dots and an acute on u. In Hanyu Pinyin it marks the second tone on ü. HTML5 defines no named entity for it.

Unicode U+01D8

All of these produce the same glyph: ǘ. Prefer a pasted ǘ in UTF-8 pages; use numeric or CSS forms when you need an escape.

Four ways to produce ǘ in a single document (no named entity).
Using Hex Code: ǘ

Using Direct Character: ǘ
Using CSS Entity: ǘ
How It Works
1. Hex:U+01D8 → ǘ in HTML. Reliable numeric form.
2. Decimal: same code point as 472 → ǘ. Same glyph.
3. Direct: paste ǘ in a UTF-8 file with <meta charset="UTF-8">.
4. CSS: use \01D8 in content (not an HTML entity). #point::after appends that ǘ after the paragraph text.
Pitfalls & Tips
Common mistakes when working with the u diaeresis acute entity.
Named
No named entity
HTML5 has no &... name for U+01D8 — use hex or decimal instead.
CSS vs HTML
Do not mix escapes
\01D8 belongs in CSS. ǘ / ǘ belong in HTML.
Look-alikes
Not plain ü
Umlaut ü is U+00FC (ü). This letter adds an acute for Pinyin tone 2.
Case
ǘ vs Ǘ
Uppercase is U+01D7 — a different code point from U+01D8.
Semicolon
End references
Always finish with ; — write ǘ, not ǘ.
UTF-8
Declare charset
If you paste ǘ directly, serve the page as UTF-8 with <meta charset="UTF-8">.
