Mathematical Double-struck Capital U Symbol
π is the Mathematical Double-Struck Capital U character used in mathematical notation.
U+1D54C
π (MATHEMATICAL DOUBLE-STRUCK CAPITAL U) is a Unicode math character often found in textbooks and typeset formulas. Use it when you need a distinct double-struck βUβ style in your writing or design. This page helps you copy the symbol and understand its standard identity.
Mathematical Double-struck Capital U Symbol Meaning
The character π is a βdouble-struckβ (also called double-outline) capital U used primarily in mathematical typesetting. In many contexts it represents specific sets or number systems (for example, symbols denoting standard mathematical collections), but the exact meaning depends on the notation used by a particular text or author. Because it is a dedicated Unicode math character, it is best treated as a distinct glyph rather than a stylized substitute for a normal βUβ. When precise typography matters, copy π rather than approximating it with fonts or styling.
Common uses
- β’Mathematical set and domain notation in formulas
- β’Typesetting documents that require a double-struck capital U glyph
- β’Labeling variables or named objects in academic writing
- β’Designing math posters, slide titles, or infographics with correct Unicode characters
- β’Web and app content where you need consistent rendering of the math symbol

What is the Unicode code point for π?
π is U+1D54C (MATHEMATICAL DOUBLE-STRUCK CAPITAL U).
How do I copy π in HTML?
You can use the HTML entity 𝕌 or copy the character directly.
How do I include π in CSS or JavaScript?
CSS escape: \\1D54C. JavaScript escape: \\u{1D54C}.
Is π interchangeable with a normal capital βUβ?
No. π is a distinct Unicode math glyph (double-struck). A normal βUβ wonβt match its intended typographic style.
