🧠 How It Works

1

Hexadecimal Code

&#x104; uses the Unicode hexadecimal value 104 to display the character. The x prefix indicates hexadecimal format.

HTML markup
2

Decimal HTML Code

&#260; uses the decimal Unicode value 260 to display the same character. A common method for Latin Extended-A characters.

HTML markup
3

Named Entity

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

HTML markup
4

CSS Entity

\104 is used in CSS stylesheets, particularly in the content property of pseudo-elements like ::before and ::after.

CSS stylesheet
=

Same visual result

All four methods produce the glyph: Ą. Unicode U+0104 sits in Latin Extended-A. Lowercase equivalent: U+0105 (&aogon;). Do not confuse with plain A (U+0041).

Use Cases

The uppercase A ogonek (Ą) is commonly used in:

🇵🇱 Polish

All-caps text, headings, and words like SĄ (they are) where the nasal vowel requires Ą.

🌐 Lithuanian

Used in Lithuanian orthography. Correct rendering is required for i18n content.

📝 Proper names

Names of people, cities, and brands that include Ą must display correctly for accessibility and SEO.

🔤 Education

Language learning apps, dictionaries, and phonetic content teaching Polish and Lithuanian spelling.

📄 Publishing

Legal, academic, and editorial content in Polish or Lithuanian.

🎨 Typography

Headlines, logos, and styled text requiring correct Polish or Lithuanian spelling.

🔍 Search & SEO

Correct rendering so users can find content with proper ogonek spelling in all-caps queries.

💡 Best Practices

Do

  • Use &Aogon; in HTML when possible for readability
  • Serve pages as UTF-8; you can also type Ą directly in UTF-8 source
  • Set lang="pl" or lang="lt" on relevant content
  • Use fonts that support Latin Extended-A characters
  • Distinguish Ą (ogonek) from plain A (U+0041)

Don’t

  • Substitute plain A when Ą is required for correct spelling
  • Confuse Ą (ogonek) with Ā (macron) or other accented A variants
  • Put CSS escape \104 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 Ą; named entity is most readable
