This character is a Other Symbol and is commonly used, that is, in no specific script. The character is also known as delete to the left 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+232B forms with similar adjacent characters prevents a line break inside it.
The Wikipedia has the following information about this codepoint:
Backspace (← Backspace) is the keyboard key that in typewriters originally pushed the carriage one position backwards, and in modern computer systems typically moves the display cursor one position backwards, deletes the character at that position, and shifts back any text after that position by one character.
