This character is a Other Symbol and is commonly used, that is, in no specific script. The character is also known as compass.
The glyph is not a composition. It has no designated width in East Asian texts. In bidirectional text it acts as Other Neutral. When changing direction it is not mirrored. The word that U+263C forms with similar adjacent characters prevents a line break inside it.
The Wikipedia has the following information about this codepoint:
A solar symbol is a symbol representing the Sun.
Common solar symbols include circles (with or without rays), crosses, and spirals.
In religious iconography, personifications of the Sun or solar attributes are often indicated by means of a halo or a radiate crown.
When the systematic study of comparative mythology first became popular in the 19th century, scholarly opinion tended to over-interpret historical myths and iconography in terms of "solar symbolism".
This was especially the case with Max Müller and his followers beginning in the 1860s in the context of Indo-European studies. Many "solar symbols" claimed in the 19th century, such as the swastika, triskele, Sun cross, etc. have tended to be interpreted more conservatively in scholarship since the later 20th century.
