Mathematical Italic Capital H 𝐻
Visual Description: The glyph is a tall H with a light tilt. It keeps the vertical strokes but leans to the right. The stroke width is even and the curves are subtle. It looks like a stylized letter used in formulas rather than normal text.
Meaning & Usage: This is a mathematical style choice. Uppercase H in italics marks a quantity name rather than a fixed symbol. It helps readers see variables, vectors, or constants in formulas. In software, it appears in formulas, calculators, and quick UI controls for operations or comparisons.
Historical Background: The italic style of Latin letters grew with early mathematical writing. Designers created a family of mathematical alphanumeric symbols to keep symbols and text separate. This H belongs to that tradition, offering a distinct look without changing the underlying meaning. Over time, fonts and typesetting tools made it common in digital math.
Practical Use: In calculations and problem solving, italic H helps distinguish the symbol as a variable or quantity. It appears in equations, height measurements, or labels in diagrams. Editors, calculators, and UI tools let you switch to italic glyphs to enter formulas or to compare values quickly.

How to type / insert
Fast copy: click the Copy button near the top of this page.
By codepoint: in many editors and IDEs, you can insert via the Unicode code U+1D43B or a built‑in character picker.
HTML: use the numeric entity 퐻 (hex) or 퐻 (decimal) when an HTML entity is needed.
Compatibility & troubleshooting
Font support: if the symbol does not render, the current font likely lacks this codepoint. Choose a font with broad Unicode coverage or allow a fallback font.
Web pages: ensure your CSS font stack includes a general fallback; avoid relying on images for common symbols to preserve accessibility and copyability.
