What You'll Learn

How to display the uppercase I with stroke (Ɨ) in HTML using hexadecimal, decimal, and CSS escape methods. The horizontal stroke through the letter distinguishes it from plain I. It is U+0197 (LATIN CAPITAL LETTER I WITH STROKE) in the Latin Extended-B block.

Render it with Ɨ, Ɨ, or CSS escape \197. There is no named HTML entity for this character. The lowercase pair is ɨ (barred i, U+0268, IPA Extensions).

🧠 How It Works

1

Hexadecimal Code

&#x197; uses the Unicode hexadecimal value 197 to display the character. The x prefix indicates hexadecimal format.

HTML markup
2

Decimal HTML Code

&#407; uses the decimal Unicode value 407 to display the same character. A common method for Latin Extended-B characters.

CSS Entity

\197 is used in CSS stylesheets, particularly in the content property of pseudo-elements like ::before and ::after.

CSS stylesheet
=

Same visual result

All three methods produce the glyph: Ɨ. Unicode U+0197 sits in Latin Extended-B. Lowercase equivalent: U+0268 (ɨ, barred i). There is no named HTML entity. Do not confuse with plain I (U+0049) or ı (dotless i).

Use Cases

The uppercase I stroke (Ɨ) is commonly used in:

💡 Best Practices

Do

  • Use &#407; or &#x197; in HTML (no named entity exists)
  • Serve pages as UTF-8; you can also type Ɨ directly in UTF-8 source
  • Distinguish Ɨ from plain I, ɨ (lowercase), and ı (dotless i)
  • Use fonts that support Latin Extended-B characters
  • Link to the lowercase pair ɨ (U+0268) when documenting case forms

Don’t

  • Substitute plain I (U+0049) when Ɨ is required
  • Confuse Ɨ (uppercase stroke) with ɨ (lowercase barred i) in case-sensitive text
  • Put CSS escape \197 in HTML text nodes
  • Use padded Unicode notation like U+00197—the correct value is U+0197
  • Use \00197 in CSS—the correct escape is \197
