U+2113. The cursive small l, which Unicode also calls mathematical symbol 'ell' and the traditional symbol for the liter. \ell in LaTeX, ℓ in HTML.

The cursive l symbol is ℓ, U+2113, Script small l: the lowercase letter as handwriting draws it. Its capital is ℒ, U+2112. Math has a second small one, 𝓁, and the bold pair 𝓵 and 𝓛.

The cursive l in math
A small ℓ is the fancy l of a formula, written to keep the letter apart from the digit 1: for the length of an interval, for the sequence spaces ℓ¹ and ℓ², and in physics for the azimuthal quantum number. The capital ℒ marks the Laplace transform, as in ℒ{f}, a Lagrangian density, a likelihood function and the Lie derivative.
ℓ and the liter
ℓ is the traditional symbol for the liter, and one-character units such as ㎖ are built from it. The official symbols are plain letters: l since 1879 and, since 1979, also L, which cannot be taken for the number 1.
In LaTeX, \ell sets ℓ and \mathcal{L} a calligraphic capital; \mathscr{L}, from the mathrsfs package, sets it in a formal script font.
Questions and answers
How do I type the cursive l symbol?
No key makes ℓ, and it is in neither Alt code table. In a web page write ℓ. Apps that read an Alt code above 255 as a code point, rich text editors among them, type it with Alt+8467.
Is there a cursive capital L symbol?
Yes: ℒ, U+2112, Script capital L, with 𝓛 as its bold form. The script alphabet of math skips the plain capital L, because ℒ was already encoded and a second one would be a duplicate. In HTML it is ℒ.
What is the difference between ℓ and 𝓁?
Both are a cursive lowercase l. ℓ is the older sign and, by Unicode’s own note, derives from a special italic form of the letter despite its name. 𝓁, U+1D4C1, is the l of the mathematical script alphabet, added in 2003.
Which is the loopy cursive l?
ℓ: a small l drawn as one tall loop. The curly letters ȴ and ɬ are not math signs. ȴ is an l with a curl from Unicode’s additions for Sinology, and ɬ an l with a belt from the International Phonetic Alphabet.
