html
<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <title>Uppercase I Stroke</title>
  <style>
    #point::after {
      content: "\0197";

<body>
  <p>Using Hex Code: &#x0197;</p>

  <p id="point">Using CSS Entity: </p>
  <p>Typed directly: &#x0197;</p>
  <p>Compare: I &#x0197; &#x0268;</p>
</body>
</html>
Try It Yourself

How It Works

1. Hex: U+0197 → &#x0197; in HTML. The browser turns it into the glyph.

2. Decimal: same code point as 407 → &#407;. Same result as hex.

3. CSS: use \0197 in content (not an HTML entity). #point::after appends that glyph after the paragraph text.

4. Compare: plain I, uppercase stroke Ɨ, and lowercase stroke ɨ are three different characters.

Pitfalls & Tips

Common mistakes when working with this character.

Named?

No named entity

HTML5 does not define a named entity for U+0197. Use numeric forms.

Look-alikes

Not plain I

U+0197 includes the stroke. Do not replace it with U+0049 when the stroke is required.

Case

Use the correct case pair

Lowercase is U+0268 (&#x0268; / &#616;) in IPA Extensions — not a nearby Latin Extended-B code point.

Fonts

Check Extended-B coverage

Some fonts omit U+0197. Prefer fonts with good Latin Extended-B / phonetic support.

CSS vs HTML

Do not mix escapes

\0197 belongs in CSS. &#x0197; / &#407; belong in HTML.

Semicolon

End references

Always finish with ; — write &#407;, not &#407.

Compatibility

Browser Support

Uppercase I Stroke / LATIN CAPITAL LETTER I WITH STROKE (U+0197) and its numeric entity forms (&#x0197;, &#407;, CSS \\0197) are supported in all mainstream browsers. Glyph shape depends on Latin Extended-B font coverage.
