What You'll Learn

How to display the uppercase S with acute accent (Ś) in HTML using named entity, hexadecimal, decimal, and CSS escape methods. This character is U+015A in the Latin Extended-A block. It is essential in Polish (e.g. Święty — holy, Śląsk — Silesia), Kashubian, and Lower Sorbian orthography, where it represents a voiceless alveolo-palatal fricative (similar to English “sh”).

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

🎨 CSS Generated Content

Using \015A in the CSS content property to insert Ś via pseudo-elements.

💡 Best Practices

Do

  • Serve pages as UTF-8; you can type Ś directly in UTF-8 source
  • Use &Sacute; for readable HTML when a named form is preferred
  • Set lang="pl" on Polish content for correct pronunciation hints
  • Use \015A in CSS content when generating the symbol via pseudo-elements
  • Distinguish Ś (acute) from Š (caron) and plain S (U+0053)

Don’t

  • Substitute plain S when Ś is required in Polish text
  • Confuse Ś (acute, Polish) with Š (caron, Czech/Slovak š)
  • Confuse Ś with &sect; (section sign, U+00A7)
  • Put CSS escape \015A in HTML text nodes
  • Use \0015A in CSS—the correct escape is \015A
