U+03F1 "ϱ" Greek Rho Symbol Unicode Character
Unicode Version 17.0
ϱ
U+03F1 "ϱ" Greek Rho Symbol is a typographic variant of the lowercase Greek letter rho, distinct from the standard rho (ρ) in its curled or rounded tail. While the standard rho resembles Latin lowercase "p" in many fonts, the symbol ϱ often has a longer, looping descender that extends below the baseline, making it visually similar to a cursive "r." In Unicode, it is classified as a lowercase Greek letter and is frequently used in mathematical and scientific contexts to represent resistively or density, particularly in fluid dynamics and statistics, though its precise usage depends on the convention adopted by a given field.
