🧠 How It Works

1

Hexadecimal Code

&#xC4; uses the Unicode hexadecimal value C4 to display the character. The x prefix indicates hexadecimal format.

HTML markup
2

Decimal HTML Code

&#196; uses the decimal Unicode value 196 to display the same character. One of the most commonly used methods in HTML.

3

Named Entity

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

4

CSS Entity

\00C4 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: Ä. Unicode U+00C4 sits in Latin-1 Supplement. Lowercase equivalent: U+00E4 (&auml;). Do not confuse with plain A (U+0041) or  (circumflex).

Use Cases

💡 Best Practices

Do

  • Use &Auml; in HTML when possible for readability
  • Serve pages as UTF-8; you can also type Ä directly in UTF-8 source
  • Set lang="de", lang="sv", or lang="fi" on relevant content
  • Use fonts that support Latin-1 Supplement characters
  • Distinguish Ä (umlaut) from plain A (U+0041) and  (circumflex)

Don’t

  • Substitute plain A or AE when Ä is required for correct German spelling
  • Confuse Ä (umlaut) with à (tilde) or other accented A variants
  • Put CSS escape \00C4 in HTML text nodes
  • Assume all fonts render Latin-1 glyphs identically
  • Mix entity styles randomly in one file

Key Takeaways

1

Four references render Ä; named entity is most readable
