U+269D OUTLINED WHITE STAR

The Wikipedia has the following information about this codepoint:

A pentagram (sometimes known as a pentalpha, pentangle, or star pentagon) is the shape of a regular five-pointed star polygon, formed from the diagonal line segments of a convex (or simple, or non-self-intersecting) regular pentagon. Drawing a circle around the 5 points creates a similar symbol referred to as the pentacle, which is used widely by Wiccans, pagans, or just as a sign of life and connections. The word "pentagram" refers only to the five-pointed star, not the circle surrounding it in a pentacle.

Pentagrams were used symbolically in ancient Greece and Babylonia, today they are widely used by the Wicca, witches, and pagans, akin to the use of the cross by Christians. The pentagram has magical associations. Many people who practice Modern Paganism and Pagan faiths wear jewelry incorporating the symbol. Christians once commonly used the pentagram to represent the five wounds of Jesus.

The word pentagram comes from the Greek word πεντάγραμμον (pentagrammon), from πέντε (pente), "five" + γραμμή (grammē), "line". Pentagram refers to just the star and pentacle refers to the star within the circle specifically although these are often referred to as the same. The word pentalpha is a learned modern (17th-century) revival of a post-classical Greek name of the shape.
