🧠 How It Works

1

Hexadecimal Code

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

HTML markup
2

Decimal HTML Code

&#205; uses the decimal Unicode value 205 to display the same character. A common method for Latin-1 characters.

HTML markup
3

Named Entity

&Iacute; is the standard named entity for Í—readable in source HTML and part of the HTML Latin-1 entity set.

4

CSS Entity

\CD 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: Í. Unicode U+00CD sits in Latin-1 Supplement. Lowercase equivalent: U+00ED (&iacute;). Do not confuse with plain I (U+0049).

Use Cases

💡 Best Practices

Do

  • Use &Iacute; in HTML when possible for readability
  • Serve pages as UTF-8; you can also type Í directly in UTF-8 source
  • Set lang attributes (e.g. lang="es") for correct pronunciation
  • Use fonts that support Latin-1 Supplement characters
  • Distinguish Í (U+00CD) from plain I (U+0049)—meaning can change in proper names

Don’t

  • Substitute plain I when Í is required for correct spelling
  • Confuse Í with Ì (I grave) or other I variants
  • Put CSS escape \CD in HTML text nodes
  • Assume all fonts render accented Latin-1 glyphs identically
  • Omit UTF-8 encoding on pages with accented characters
