U+1D6FF MATHEMATICAL ITALIC SMALL DELTA: 𝛿 – Unicode

U+1D6FF was added in Unicode version 3.1 in 2001. It belongs to the block U+1D400 to U+1D7FF Mathematical Alphanumeric Symbols in the U+10000 to U+1FFFF Supplementary Multilingual Plane.

This character is a Lowercase Letter and is commonly used, that is, in no specific script.

The glyph is a font version of the glyph Greek Small Letter Delta. It has no designated width in East Asian texts. In bidirectional text it is written from left to right. When changing direction it is not mirrored. The word that U+1D6FF forms with similar adjacent characters prevents a line break inside it. The glyph can be confused with one other glyph.

The Wikipedia has the following information about this codepoint:

Delta (; uppercase Δ, lowercase δ; Greek: δέλτα, délta, [ˈðelta]) is the fourth letter of the Greek alphabet. In the system of Greek numerals it has a value of 4. It was derived from the Phoenician letter dalet 𐤃. Letters that come from delta include Latin D and Cyrillic Д.
A river delta (originally, the delta of the Nile River) is so named because its shape approximates the triangular uppercase letter delta. Contrary to a popular legend, this use of the word delta was not coined by Herodotus.
