Uppercase H Circumflex (Ĥ) is the Latin Extended-A character at Unicode U+0124 (LATIN CAPITAL LETTER H WITH CIRCUMFLEX). HTML5 names it Ĥ. Use it for Esperanto and other Latin-script text that needs Ĥ.

Not the same ĥ (ĥ) · H · Ȟ
Named, hex, decimal, CSS, and a typed character all produce the same glyph: Ĥ. Prefer Ĥ or Ĥ in HTML markup. For the lowercase form see ĥ; for H with caron see uppercase H caron.

How It Works
1. Named:Ĥ is the HTML5 name for U+0124 → Ĥ (case-sensitive: capital H).
2. Hex / decimal:Ĥ or Ĥ insert the same code point.
3. Typed: in a UTF-8 document you can paste Ĥ directly — same glyph, no entity.
4. CSS: use \0124 in content (not an HTML entity). #point::after appends that Ĥ after the paragraph text.
5. Esperanto:lang="eo" marks the language; Ĥoro spells Ĥoro (choir).
Pitfalls & Tips
Common mistakes when working with Uppercase H Circumflex.
Case
Named entity is case-sensitive
Ĥ is capital H. ĥ is the lowercase letter ĥ, not a synonym.
Plain H
Not the same as plain H
Plain H (U+0048) has no circumflex. Do not substitute it when Ĥ is required for correct spelling.
Caron
Not H with caron
U+021E (Ȟ) uses a caron (háček), not a circumflex. See uppercase H caron.
Prefer named
Prefer Ĥ in HTML
The named form is easier to read in source than numeric codes. Use hex/decimal when you need numeric-only markup.
CSS vs HTML
Do not mix escapes
\0124 belongs in CSS strings. Ĥ / Ĥ / Ĥ belong in HTML.
Fonts
Need Latin Extended-A coverage
Some fonts omit U+0124. Prefer fonts that cover Latin Extended-A (U+0100–U+017F).

Bottom line: Prefer Ĥ in HTML text. Use Ĥ / Ĥ as equivalents, and \\0124 only inside CSS content.
Remember
Key Takeaways
Unicode: this letter is U+0124 (decimal 292) — glyph Ĥ.
HTML: prefer Ĥ, or use Ĥ / Ĥ.
CSS: use \0124 inside content for generated text.
Watch out: Ĥ ≠ plain H ≠ H caron Ȟ · Ĥ ≠ ĥ.
Use Ĥ (named), Ĥ (hex), Ĥ (decimal), or the CSS escape \0124 in the content property. All render Ĥ. Prefer Ĥ or Ĥ for readable markup.
U+0124 (LATIN CAPITAL LETTER H WITH CIRCUMFLEX). Hex 0124, decimal 292, named entity Ĥ. It belongs to Latin Extended-A (U+0100–U+017F).
Yes. HTML5 defines Ĥ for U+0124. It is case-sensitive — write Hcirc with a capital H. Lowercase ĥ is a different character (ĥ).
U+0124 (Ĥ) is capital H with a circumflex. U+0048 is plain H. U+021E is H with a caron (háček) — a different accent used in Lakota and Finnish Kalo.
Use it for Esperanto (for example Ĥoro = choir), Chinook Jargon, and other Latin-script text that needs capital H with circumflex.
HTML entities (Ĥ, Ĥ, or Ĥ) go in markup. The CSS escape \0124 is used in stylesheets (usually in the content property of ::before/::after). Both render Ĥ.
