What You'll Learn

How to display the lowercase o with ogonek (ǫ) in HTML using hexadecimal, decimal, and CSS escape methods. This character is U+01EB in the Latin Extended-B block. The ogonek (hook) below the letter marks a nasal or historically distinct vowel—notably in Navajo orthography and in historical or linguistic Lithuanian texts.

Render it with ǫ, ǫ, or CSS escape \01EB. There is no named HTML entity for this character (unlike į for į). In UTF-8 documents you can also type ǫ directly.

💡 Best Practices

Do

  • Serve pages as UTF-8; you can type ǫ directly in UTF-8 source
  • Use numeric references (&#x01EB; or &#491;) when escaping is required
  • Set lang="nv" on Navajo content blocks
  • Use fonts that support Latin Extended-B (U+0180–U+024F)
  • Distinguish ǫ from ą (a ogonek), į (i ogonek), and plain o

Don’t

  • Use ǫ for standard modern Lithuanian—use ą, ę, į, or ų instead
  • Substitute plain o when ǫ is required in Navajo text
  • Expect a named HTML entity—none exists for ǫ
  • Put CSS escape \01EB in HTML text nodes
  • Double-encode numeric references in dynamically generated HTML

Key Takeaways

1

Type ǫ directly, or use hex/decimal references
