U+1D707 "𝜇" Mathematical Italic Small Mu Unicode Character

Unicode Version 17.0

𝜇

U+1D707 "𝜇" Mathematical Italic Small Mu is a stylized version of the Greek letter mu, belonging to the Mathematical Alphanumeric Symbols block and designed specifically for use in scientific and mathematical notation. It represents the same basic letter as the standard Greek small mu (U+03BC) but in an italic typeface, which helps distinguish it from surrounding text in formulas where variables and constants are commonly italicized. This character is frequently employed in fields such as physics and engineering to denote the coefficient of friction, the reduced mass in a two body problem, magnetic dipole moment, or the permeability of a material, as well as in statistics to represent the population mean. By encoding it as a distinct mathematical symbol, Unicode ensures consistent rendering across different digital platforms, preserving its intended italic form and semantic role in complex equations instead of relying on font based styling that may be lost during text processing.
