Mathematical Fraktur Capital B 𝔅
Visual Description: A stylized capital B drawn in Fraktur style. It has thick and thin strokes, sharp angles, and decorative curves. The lines resemble old print, with a Gothic look. The character is used in math and typography to signal special objects. It stands out in equations on paper and screens.
Meaning & Usage: In mathematics and logic, such letters mark special objects. A Fraktur B can denote a substructure, like a subalgebra or a descriptive set. It is a stylistic choice rather than a rule of notation. In software, it appears in palettes that let you select font styles. It helps comparisons by visual separation.
Historical Background: Fraktur style comes from older print traditions. It was popular in German writing and in early math texts. Mathematicians adopted multiple typefaces to distinguish objects. The use of ornate letters grew with typesetting and notation systems. The idea is to create visual variety without changing meaning.
Practical Use: Use this letter to name a set, a substructure, or a distinguished object. On calculators and math apps, there may be a quick UI control to switch to a Fraktur font for emphasis or for comparisons. In teaching, stylized letters aid memory and distinction between symbols. Keep notation consistent across a problem.

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+1D505 or a built‑in character picker.
HTML: use the numeric entity 픅 (hex) or 픅 (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.
