U+1D57E
𝕾 is a Unicode character from the Mathematical Bold Fraktur set. It’s commonly used when you want an “S” with a specific bold fraktur look in math and design. You can copy it directly or insert it via Unicode escape codes.
Mathematical Bold Fraktur Capital S Symbol Meaning
𝕾 (U+1D57E) is “Mathematical Bold Fraktur Capital S,” a styled uppercase letter from the Unicode Math/Fraktur-inspired alphabets. In practice, it’s used to represent variables, sets, operators, or named quantities in documents where typography needs to be consistent with mathematical styling. Because it is a dedicated Unicode character (not plain ASCII “S”), it preserves the intended visual form across platforms that support it. It may be used alongside other bold fraktur letters to create a matching alphabet style in equations, posters, UI labels, or generated math text.
Common uses
- •Labeling variables in handwritten-style or stylized math notation
- •Creating consistent typographic branding for mathematical diagrams and charts
- •Using in design mockups where a fraktur-like bold “S” is required
- •Posting math-related content (equations, summaries, or notes) with proper Unicode styling
- •Developers: rendering the exact glyph via Unicode in HTML/CSS/JavaScript
