U+2625 Ankh

The Wikipedia has the following information about this codepoint:

The ankh or key of life is an ancient Egyptian hieroglyphic symbol used to represent the word for "life" and, by extension, as a symbol of life itself.

The ankh has a T-shape topped by a droplet-shaped loop. It was used in writing as a triliteral sign, representing a sequence of three consonants, Ꜥ-n-ḫ. This sequence was found in several Egyptian words, including the terms for "mirror", "floral bouquet", and "life". The symbol often appeared in Egyptian art as a physical object representing either life or related life-giving substances such as air or water. Commonly depicted in the hands of ancient Egyptian deities, sometimes being given by them to the pharaoh, it represents their power to sustain life and to revive human souls in the afterlife.

The ankh was a widespread decorative motif in ancient Egypt, also used decoratively by neighbouring cultures. Copts adapted it into the crux ansata, a shape with a circular rather than droplet loop, and used it as a variant of the Christian cross. The ankh came into widespread use in Western culture in the 1960s, appearing as a symbol of African cultural identity, Neopagan belief systems, and later, the goth subculture.
