🧠 How It Works
Hexadecimal Code
Ǖ uses the Unicode hexadecimal value 01D5 to display the character. The x prefix indicates hexadecimal format.
Decimal HTML Code
Ǖ uses the decimal Unicode value 469 to display the same character. A common method when a numeric reference is needed.
Direct Character
Type Ǖ directly in HTML when your document uses UTF-8 encoding. There is no named entity for this combined diacritic symbol.
CSS Entity
\01D5 is used in CSS stylesheets, particularly in the content property of pseudo-elements like ::before and ::after.
Same visual result
All methods produce the glyph: Ǖ. Unicode U+01D5 sits in Latin Extended-B. Lowercase equivalent: U+01D6 (ǖ). Do not confuse with Ü (diaeresis only), Ǘ (diaeresis + acute), Ǚ (diaeresis + caron), or other precomposed ü-tone letters in the U+01D6–U+01DC range.
Use Cases
The uppercase U diaeresis macron (Ǖ) is commonly used in:
Represents the capitalized first tone of ü in Pinyin romanization (e.g. NǕ, LǕ) and tone-chart reference material.
Chinese courses, textbooks, and apps teaching the four tones of ü with precomposed Unicode letters.
Phonetic transcription and linguistic descriptions using U with both diaeresis and macron marking.
Romanization systems and dictionaries requiring extended Latin characters with combined diacritics.
Papers, character charts, and language resources requiring precise precomposed character representation.
Using the correct character (U+01D5) with lang="zh-Latn" helps assistive technologies interpret Pinyin correctly.
When building HTML from Pinyin data, using Ǖ or Ǖ guarantees correct output.
💡 Best Practices
Do
- Serve pages as UTF-8; you can type Ǖ directly in UTF-8 source
- Use numeric references (
ǕorǕ) when escaping is required - Use
\01D5in CSScontentwhen generating the symbol via pseudo-elements - Use fonts that support Latin Extended-B characters (U+0180–U+024F)
- Distinguish Ǖ from Ü (diaeresis only) and other ü-tone letters (ǖ, ǘ, ǚ, ǜ)
Don’t
- Confuse Ǖ with Ü (Ü) or plain U with separate accent markup when the precomposed character is required
- Expect a named HTML entity—none exists for Ǖ
- Use the old incorrect CSS escape
\001D5—the correct value is\01D5 - Put CSS escape
\01D5in HTML text nodes - Double-encode numeric references in dynamically generated HTML
