Mathematical Bold Italic Small Phi Symbol
๐ is the mathematical bold italic form of the lowercase Greek letter phi (ฯ).
U+1D74B
๐ is a Unicode math symbol: โMATHEMATICAL BOLD ITALIC SMALL PHIโ (U+1D74B). Itโs used when you want a bold, italic style variant of the lowercase phi character in formulas and design.
Mathematical Bold Italic Small Phi Symbol Meaning
๐ (U+1D74B) is the mathematical bold italic small phi. It represents the Greek letter phi (ฯ), specifically in a typographic style intended for mathematical notationโbold and italicโrather than the regular italic ฯ. Youโll commonly see it in typeset equations where authors differentiate variables by font weight and slant, for example distinguishing a bold italic phi from other phi variants. In practice, its usefulness depends on the font and math rendering support: if your document or app lacks that math font, the glyph may not display as intended.
Common uses
- โขMathematical formulas that require bold italic phi for a variable name
- โขDifferentiating multiple phi variables in typeset equations
- โขTypography for math posters, slide decks, and reports needing consistent math styling
- โขWeb or app UI text where you want a specific math glyph for branding or notation
- โขDeveloper-friendly copy/paste of the exact Unicode character for labels and documentation

FAQ
What does the Mathematical Bold Italic Small Phi symbol mean?
๐ (U+1D74B) is the mathematical bold italic small phi. It represents the Greek letter phi (ฯ), specifically in a typographic style intended for mathematical notationโbold and italicโrather than the regular italic ฯ. Youโll commonly see it in typeset equations where authors differentiate variables by font weight and slant, for example distinguishing a bold italic phi from other phi variants. In practice, its usefulness depends on the font and math rendering support: if your document or app lacks that math font, the glyph may not display as intended.
Is ๐ the same as the normal lowercase phi (ฯ)?
Not exactly. ๐ is the mathematical bold italic small phi (Unicode U+1D74B), while ฯ is the standard Greek small phi. They look similar in meaning but differ in font style and code point.
What is the Unicode code point for ๐?
๐ is U+1D74B. Its HTML entity is 𝝋, and it can be referenced in code with the escapes shown on this page.
Why doesnโt ๐ display correctly in my document?
Math alphabets depend on font support. If your font or app doesnโt include this glyph, it may render incorrectly or fallback to a different character.
Where should I use ๐ instead of ฯ?
Use ๐ when you specifically need the bold italic phi styling to match a typographic convention in math writing, design, or notation that distinguishes variables by weight and slant.
