This character is a Other Symbol and is commonly used, that is, in no specific script.
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+23D7 forms with similar adjacent characters prevents a line break inside it.
The Wikipedia has the following information about this codepoint:
Scansion ( SKAN-shən, rhymes with mansion; verb: to scan), or a system of scansion, is the method or practice of determining and (usually) graphically representing the metrical pattern of a line of verse. In classical poetry, these patterns are quantitative based on the different lengths of each syllable, while in English poetry, they are based on the different levels of stress placed on each syllable. In both cases, the meter often has a regular foot. Over the years, many systems have been established to mark the scansion of a poem.
