This character is a Other Symbol and is commonly used, that is, in no specific script. The character is also known as clear key.
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+2327 forms with similar adjacent characters prevents a line break inside it.
