What You'll Learn

How to display the Combining Double Tilde (͠) in HTML using hexadecimal, decimal, and CSS entity methods. This character is U+0360 (COMBINING DOUBLE TILDE) in the Combining Diacritical Marks block (U+0300–U+036F)—a combining diacritic used in linguistic notation, phonetic transcription, and specialized typography.

There is no named HTML entity for U+0360. Use ͠, ͠, or \0360 in CSS content. U+0360 typically combines with the preceding character (e.g. a͠). Do not confuse with U+0361 (ligature tie) or U+035D (combining double breve).

💡 Best Practices

Do

  • Use &#x0360; or &#864; for U+0360
  • Use phonetic fonts (Charis SIL, Doulos SIL, Noto Sans) for combining marks
  • Test combining behavior with base letters in target browsers
  • Use UTF-8 (<meta charset="utf-8">) on all pages
  • Use \0360 only inside CSS content

Don’t

  • Assume a named entity exists for U+0360—it does not
  • Confuse U+0360 with U+0361 (ligature tie) or U+035D (double breve)
  • Expect every font to render combining marks correctly
  • Put CSS escape \0360 in HTML text nodes
  • Forget that U+0360 is a combining character—pair it with base letters

Key Takeaways

1

No named entity—use numeric references

&#x0360; &#864;
2

For CSS stylesheets, use the escape in the content property
