Hexadecimal Code

Use Cases
The lowercase u diaeresis acute (ǘ) is commonly used in:
Represents the second tone of ü in Pinyin romanization (e.g. nǘ, lǘ) 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 acute marking.
Romanization systems and dictionaries requiring extended Latin characters with combined diacritics.
Papers, character charts, and language resources requiring precise precomposed character representation.

- Use numeric references (
ǘorǘ) when escaping is required - Use

Don’t
- Confuse ǘ with ü (ü) or plain u with separate accent markup when the precomposed character is required

- Use the old incorrect CSS escape
\001D8—the correct value is\01D8 - Put CSS escape
