What Is Uppercase J Middle Stroke?

Uppercase J Middle Stroke (Ɉ) is the Latin Extended-B character at Unicode U+0248 (LATIN CAPITAL LETTER J WITH STROKE). A horizontal bar crosses the stem of capital J. There is no named HTML entity — use hex or decimal codes for phonetic, linguistic, and transliteration text.

Remember
Character     Ɉ
Unicode       U+0248
Named entity  (none)
Hex entity    Ɉ
Decimal       Ɉ
CSS escape    \0248
Not the same  J · ɉ · Ĵ

Hex, decimal, CSS, and a typed character all produce the same glyph: Ɉ. Prefer Ɉ in HTML markup. For plain capital J see uppercase J; for the lowercase pair see lowercase J middle stroke (U+0249).

Try It Yourself

How It Works

1. Hex / decimal: U+0248 → &#x0248; or &#584;. The browser turns either into Ɉ.

2. Typed: in a UTF-8 document you can paste Ɉ directly — same glyph, no entity.

3. CSS: use \0248 in content (not an HTML entity). #point::after appends that Ɉ after the paragraph text.

4. Case pair: lowercase is U+0249 (ɉ) — see lowercase J middle stroke.

Pitfalls & Tips

Common mistakes when working with Uppercase J Middle Stroke.

Named?

No named entity

HTML5 does not define a name for Ɉ. Use &#x0248; or &#584;.

Plain J

Not the same as plain J

Plain J (U+004A) has no stroke. Do not substitute it when Ɉ is required.

Circumflex

Not J with circumflex

U+0134 (Ĵ, &Jcirc;) uses a circumflex accent, not a middle stroke. See uppercase J circumflex.

Fonts

Need Latin Extended-B coverage

Some fonts omit U+0248. Prefer fonts that cover Latin Extended-B (U+0180–U+024F).

CSS vs HTML

Do not mix escapes

\0248 belongs in CSS strings. &#x0248; / &#584; belong in HTML.

Case

Case is significant

Ɉ (U+0248) and ɉ (U+0249) are different characters. Use the case your content requires.

Compatibility

Browser Support

Uppercase J Middle Stroke (U+0248) and its entity forms (&#x0248;, &#584;, CSS \\0248) are supported in all mainstream browsers when the page is UTF-8 and the font covers Latin Extended-B.

✓ Universal support

Uppercase J Middle Stroke (&#x0248;)

Encode with hex, decimal, CSS escape, or type the character — same Unicode code point everywhere.

Bottom line: Prefer &#x0248; in HTML text. Use &#584; as an equivalent, and \\0248 only inside CSS content. Glyph display depends on font coverage.

Remember

Key Takeaways

  • Unicode: this letter is U+0248 (decimal 584) — glyph Ɉ.
  • HTML: use &#x0248; / &#584; — no named entity.
  • CSS: use \0248 inside content for generated text.
  • Watch out: Ɉ ≠ plain J ≠ J circumflex Ĵ.

One line: U+0248 → &#x0248; / &#584; / CSS \0248 (no named entity).
