Lowercase u with diaeresis and grave (ǜ) is the Latin Extended-B character at Unicode U+01DC (LATIN SMALL LETTER U WITH DIAERESIS AND GRAVE). It stacks two dots and a grave on u. In Hanyu Pinyin it marks the fourth tone on ü. HTML5 defines no named entity for it.

How It Works
1. Hex:U+01DC → ǜ in HTML. Reliable numeric form.
2. Decimal: same code point as 476 → ǜ. Same glyph.
3. Direct: paste ǜ in a UTF-8 file with <meta charset="UTF-8">.
4. CSS: use \01DC in content (not an HTML entity). #point::after appends that ǜ after the paragraph text.
Pitfalls & Tips
Common mistakes when working with the u diaeresis grave entity.
Named
No named entity
HTML5 has no &... name for U+01DC — use hex or decimal instead.
CSS vs HTML
Do not mix escapes
\01DC belongs in CSS. ǜ / ǜ belong in HTML.
Look-alikes
Not ü or ǚ
Umlaut ü is U+00FC; ǚ is tone 3. This letter is tone 4 (grave on ü).
Case
ǜ vs Ǜ
Uppercase is U+01DB — a different code point from U+01DC.
Semicolon
End references
Always finish with ; — write ǜ, not ǜ.
UTF-8
Declare charset
If you paste ǜ directly, serve the page as UTF-8 with <meta charset="UTF-8">.
