🧠 How It Works

1

Hexadecimal Code

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

HTML markup
2

Decimal HTML Code

&#206; uses the decimal Unicode value 206 to display the same character. One of the most commonly used methods for Latin-1 characters.

HTML markup
3

Named Entity

&Icirc; is the standard named entity for Ηreadable in source HTML and part of the HTML Latin-1 entity set.

4

CSS Entity

\00CE 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: Î. Unicode U+00CE sits in Latin-1 Supplement. Lowercase equivalent: U+00EE (&icirc;). Do not confuse with plain I (U+0049), acute &Iacute; (Í), or caron &Icaron; (Ǐ).

💡 Best Practices

Do

  • Use &Icirc; in HTML when possible for readability
  • Serve pages as UTF-8; you can also type Î directly in UTF-8 source
  • Set lang attributes (e.g. lang="fr" or lang="ro") for correct pronunciation
  • Use fonts that support Latin-1 Supplement (U+0080–U+00FF)
  • Distinguish Î (circumflex) from Í (acute) and Ǐ (caron)

Don’t

  • Substitute plain I when Î is required for correct spelling
  • Confuse circumflex Î with acute Í or caron Ǐ
  • Put CSS escape \00CE in HTML text nodes
  • Use padded Unicode notation like U+000CE—the correct value is U+00CE
  • Use \000CE in CSS—the correct escape is \00CE

Key Takeaways

1

Four references render Î; named entity is most readable
