Greek Small Letter Mu
Greek mu stands in for a mean in statistics, a coefficient of friction in physics, or a micron in older unit notation. It looks identical to the separate Micro Sign character on this site, but the two sit at different Unicode code points, so a font or a search that only recognises one can miss the other. Reach for μ in equations, formulas and technical writing, where a plain keyboard falls short. It is cataloged at Unicode code point U+03BC in the math set, so it renders the same real text character in every app that supports the font, not a pasted image.
