🧠 How It Works

1

Hexadecimal Code

&#x208; uses the Unicode hexadecimal value 208 to display the character. The x prefix indicates hexadecimal format.

HTML markup
2

Decimal HTML Code

&#520; uses the decimal Unicode value 520 to display the same character. A common method for Latin Extended-B characters.

3

CSS Entity

\208 is used in CSS stylesheets, particularly in the content property of pseudo-elements like ::before and ::after.

CSS stylesheet
=

Same visual result

All three methods produce the glyph: Ȉ. Unicode U+0208 sits in Latin Extended-B. Lowercase equivalent: U+0209 (ȉ). There is no named HTML entity. Do not confuse with Ì (single grave, &Igrave;).

💡 Best Practices

Do

  • Use &#520; or &#x208; in HTML (no named entity exists)
  • Serve pages as UTF-8; you can also type Ȉ directly in UTF-8 source
  • Set appropriate lang attributes for linguistic or Slavic content
  • Use fonts that support Latin Extended-B diacritics
  • Distinguish Ȉ (double grave) from Ì (single grave) and plain I

Don’t

  • Substitute &Igrave; (Ì) when Ȉ (double grave) is required
  • Put CSS escape \208 in HTML text nodes
  • Use padded Unicode notation like U+00208—the correct value is U+0208
  • Use \00208 in CSS—the correct escape is \208
  • Assume all fonts render Latin Extended-B double-grave glyphs

Key Takeaways

1

Three references render Ȉ (no named entity)

&#x208; &#520;
2

For CSS stylesheets, use the escape in the content property
