This character is a Math Symbol and is commonly used, that is, in no specific script. The character is also known as most positive.
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 mirrored. The word that U+223E forms with similar adjacent characters prevents a line break inside it.
The CLDR project calls this character “inverted lazy s” for use in screen reading software. It assigns these additional labels, e.g. for search in emoji pickers: inverted, lazy, s.
The Wikipedia has the following information about this codepoint:
Mathematical Operators is a Unicode block containing characters for mathematical, logical, and set notation.
Notably absent are the plus sign (+), greater than sign (>) and less than sign (<), due to them already appearing in the Basic Latin Unicode block, and the plus-or-minus sign (±), multiplication sign (×) and obelus (÷), due to them already appearing in the Latin-1 Supplement block, although a distinct minus sign (−) is included, semantically different from the Basic Latin hyphen-minus (-).
