HTML Entity for Double Acute Accent (̋)
What You'll Learn
How to encode U+030B (combining double acute accent) in HTML and CSS. This mark combines with the preceding character—for example ő renders as ő and ű as ű (hungarumlaut in Hungarian).
It is defined in the Combining Diacritical Marks block (U+0300–U+036F). There is no named HTML entity for U+030B; use ̋, ̋, or \030B in CSS strings. Do not confuse with single combining acute accent (U+0301, ́).

🧠 How It Works
Hexadecimal Code
̋ references Unicode 030B in hex. Write it immediately after the base letter (for example ő).
Decimal HTML Code
̋ is decimal 779, equivalent to U+030B.
CSS Entity (Escape)
\030B inside a CSS string (for example content: "o\030B") emits the same combining sequence in generated content.
Same visual result
With base o or u, all methods yield ő or ű. Place U+030B immediately after the base letter. No named entity for U+030B.
Use Cases
The combining double acute accent (U+030B) is commonly used in:
Correct spelling of ő and ű (e.g. tű, sző) on Hungarian websites and apps.
Languages that use the double acute in dictionaries and language-learning sites.
Phonetic transcription and notation where double acute marks apply.
Academic papers, eBooks, and typography with decomposed diacritics.
HTML entity lists and Unicode tables for combining marks.
Proper rendering of Hungarian and related scripts for accessibility.
💡 Best Practices
Do
- Keep base letter and U+030B adjacent in the DOM (base first)
- Use UTF-8 and pick NFC or NFD consistently for your product
- For long-form Hungarian text, consider precomposed ő (U+0151) and ű (U+0171)
- Test fonts and line-breaking so the accent does not separate from its letter
- Use
\030Bonly inside CSS strings, not as raw HTML text
Don’t
- Place U+030B before the base letter (wrong order for Unicode)
- Confuse double acute (U+030B) with single combining acute (U+0301)
- Rely on CSS
contentfor entire paragraphs of accented prose - Mix NFC and NFD arbitrarily in the same database column without a plan
- Assume every decorative webfont positions combining marks perfectly
