🧠 How It Works

1

Hexadecimal Code

&#x209; uses the Unicode hexadecimal value 209 to display the character. The x prefix indicates hexadecimal format.

HTML markup
2

Decimal HTML Code

&#521; uses the decimal Unicode value 521 to display the same character. A common method for Latin Extended-B characters without named entities.

HTML markup
3

CSS Entity

\209 is used in CSS stylesheets, particularly in the content property of pseudo-elements like ::before and ::after.

No Named Entity

Unlike many Latin-1 letters, ȉ has no standard named HTML entity. Use numeric references or type the character directly in UTF-8 source.

=

Same visual result

All three methods produce the glyph: ȉ. Unicode U+0209 sits in Latin Extended-B. It canonically decomposes to i (U+0069) + combining double grave accent (U+030F). Uppercase equivalent: U+0208 (Ȉ).

Use Cases

The lowercase i double grave (ȉ) is commonly used in:

🗣 Tone marking

Linguistic descriptions that mark tone or prosodic features with a double grave accent.

🎓 Academic writing

Papers and books using extended Latin letters for precise notation.

📝 Transcription

Specialized transcription where diacritics encode tone or stress information.

📐 Phonetic notation

IPA and related systems where extra-low or specialized tone marks appear.

⚙ Unicode testing

Checking fonts, normalization, and rendering of uncommon diacritics.

📄 Data & search

Ensuring correct indexing and exact matching in text-heavy applications.

🌐 Internationalization

Multilingual and academic content requiring extended Latin symbols.

💡 Best Practices

Do

  • Serve pages as UTF-8; you can also type ȉ directly in UTF-8 source
  • Use &#521; or &#x209; when generating HTML programmatically
  • Pick fonts that support Latin Extended-B characters
  • Use numeric entities for portability since there is no named entity
  • Distinguish ȉ from grave ì, acute í, and circumflex î

Don’t

  • Expect a named HTML entity like &imath;—none exists for ȉ
  • Confuse double grave ȉ with single grave ì or other accented i forms
  • Put CSS escape \209 in HTML text nodes
  • Assume all fonts render Latin Extended-B glyphs identically
  • Omit UTF-8 encoding on pages with extended Latin characters

Key Takeaways

1

Use hex or decimal references—no named entity exists

&#x209; &#521;
2

For CSS stylesheets, use the escape in the content property
