🧠 How It Works

1

Hexadecimal Code

&#x0108; uses the Unicode hexadecimal value 0108 to display the character. The x prefix indicates hexadecimal format.

HTML markup
2

Decimal HTML Code

&#264; uses the decimal Unicode value 264 to display the same character. A common method for Latin Extended-A characters.

3

Named Entity

&Ccirc; is the standard named entity for Ĉ—readable in source HTML and part of the HTML5 entity set.

4

CSS Entity

\0108 is used in CSS stylesheets, particularly in the content property of pseudo-elements like ::before and ::after.

Same visual result

All four methods produce the glyph: Ĉ. Unicode U+0108 sits in Latin Extended-A. Lowercase equivalent: U+0109 (&ccirc;). Do not confuse with plain C (U+0043), Č (C caron), or Ç (C cedilla).

Use Cases

The uppercase C circumflex (Ĉ) is commonly used in:

🌍 Esperanto content

Correct spelling in Esperanto text (e.g. Ĉu, Ĉi, Ĉiam, Ĉef).

🔤 Linguistic notation

Support orthography in linguistic documentation and constructed-language resources.

📚 Language learning

Esperanto courses, dictionaries, and pronunciation guides with correct characters.

🎨 Typography

Showcase Latin Extended-A coverage in font demos and type design.

📄 Academic publishing

Linguistics papers, encyclopedias, and scholarly content about constructed languages.

🌐 Internationalization

Websites and apps serving Esperanto-speaking communities worldwide.

🔍 Search & SEO

Correct rendering so users can find content with proper accented spelling.

💡 Best Practices

Do

  • Use &Ccirc; in HTML when possible for readability
  • Serve pages as UTF-8; you can also type Ĉ directly in UTF-8 source
  • Set lang attributes (e.g. lang="eo") for correct pronunciation
  • Use fonts that support Latin Extended-A characters
  • Distinguish Ĉ (U+0108) from plain C (U+0043), Č (C caron), and Ç (C cedilla)

Don’t

  • Substitute plain C when Ĉ is required for correct spelling
  • Confuse Ĉ (circumflex) with Č (C caron) or Ç (C cedilla—different characters)
  • Put CSS escape \0108 in HTML text nodes
  • Assume all fonts render Latin Extended-A glyphs identically
  • Omit UTF-8 encoding on pages with accented characters

Key Takeaways

1

Four references render Ĉ; named entity is most readable

&#x0108; &#264; &Ccirc;
