Mathematical Bold Fraktur Capital H 𝕳
Visual Description: The glyph appears as a capital H drawn in a bold Gothic style with clean geometry. It has sharp angles and light flourishes that give a formal, old-fashioned look. The strokes are thick and even, so the letter reads clearly beside formulas. In print and on screens, it stands out in math text.
Meaning & Usage: In mathematics, this bold Fraktur variant marks objects that need emphasis or distinction from ordinary bold letters. It can denote special sets, spaces, or algebraic structures. Designers use it to create a quick visual cue. In apps, you may switch to this style to compare items side by side.
Historical Background: Fraktur has a long print history, with Gothic shapes chosen for emphasis and distinction. The mathematical bold Fraktur variant is a modern adaptation that appears in digital fonts. It is used to separate objects from ordinary text without breaking the flow of equations. The look persists in design tools.
Practical Use: In education and software, this glyph helps label special items in formulas. It can indicate a variable, a subset, or an operator with extra emphasis. Calculators and math editors may offer quick UI controls to apply this style or to switch to a contrasting font while comparing results.

HTML: use the numeric entity 핳 (hex) or 핳 (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.
