What You'll Learn

How to display the uppercase S with circumflex (Ŝ) in HTML using named entity, hexadecimal, decimal, and CSS escape methods. This character is U+015C in the Latin Extended-A block. It is one of the six diacritic letters in Esperanto orthography (e.g. Ŝati — to enjoy, Ŝipo — ship, Ŝafo — sheep), where it represents a voiceless postalveolar fricative (similar to English “sh”).

Render it with Ŝ, Ŝ, Ŝ, or CSS escape \015C. The named entity Ŝ is the most readable option in HTML source.

1

Hexadecimal Code

&#x015C; uses the Unicode hexadecimal value 015C to display the character. The x prefix indicates hexadecimal format.

HTML markup
2

Decimal HTML Code

&#348; uses the decimal Unicode value 348 to display the same character. A common method when a numeric reference is needed.

Named Entity

&Scirc; is the named entity for S circumflex—readable in source HTML and the preferred option for Esperanto content.

4

CSS Entity

\015C 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: Ŝ. Unicode U+015C sits in Latin Extended-A. Lowercase equivalent: U+015D (ŝ, &scirc;). Do not confuse with plain S (U+0053), Š (caron), or Ş (cedilla).

Use Cases

The uppercase S circumflex (Ŝ) is commonly used in:

🇵 Esperanto

Essential for correct Esperanto spelling at word starts (e.g. Ŝati, Ŝipo, Ŝafo). One of six standard diacritic letters in the Esperanto alphabet.

📚 Language Learning

Teach correct spelling and pronunciation for Esperanto and related constructed or international language content.

🌐 Multilingual Sites

Support proper rendering of Esperanto text on community sites, wikis, forums, and educational platforms.

📄 Typography & Publishing

Ensure correct character display in digital publications, dictionaries, and linguistic resources.

🔬 Linguistic & Academic

Used in phonetic notation, constructed-language studies, and academic papers referencing Esperanto orthography.

♿ Accessibility

Using the correct character (U+015C) with proper lang attributes (e.g. lang="eo") ensures assistive technologies pronounce content correctly.

🎨 CSS Generated Content

Using \015C in the CSS content property to insert Ŝ via pseudo-elements.

💡 Best Practices

Do

  • Serve pages as UTF-8; you can type Ŝ directly in UTF-8 source
  • Use &Scirc; for readable HTML when a named form is preferred
  • Set lang="eo" on Esperanto content for correct pronunciation hints
  • Use \015C in CSS content when generating the symbol via pseudo-elements
  • Distinguish Ŝ (circumflex) from Š (caron), Ş (cedilla), and plain S (U+0053)

Don’t

  • Substitute plain S when Ŝ is required in Esperanto text
  • Confuse Ŝ (circumflex) with Š (caron) or Ş (cedilla)
  • Use Š (caron) in Esperanto—Esperanto uses circumflex, not caron
  • Put CSS escape \015C in HTML text nodes
  • Use \0015C in CSS—the correct escape is \015C
