U+2113 "ℓ" Script Small L Unicode Character

U+2113 "ℓ" Script Small L is a typographic symbol that represents a script or cursive lowercase letter L, designed to look distinct from the standard Latin l to avoid confusion in scientific and mathematical contexts. It is commonly used as a symbol for liter, a unit of volume in the metric system, particularly in chemistry and medicine, as well as for representing the natural logarithm in some historical notations or other specialized formulas. This character is part of the Letterlike Symbols block in Unicode and was included to serve the need for a clear, non ambiguous glyph in technical writing where the standard lowercase L might be mistaken for the digit 1 or the uppercase letter I.
