This character is a Other Symbol and is commonly used, that is, in no specific script. The character is also known as rightward tab.
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+21E5 forms with similar adjacent characters prevents a line break inside it.
The CLDR project calls this character “rightwards arrow bar” for use in screen reading software. It assigns these additional labels, e.g. for search in emoji pickers: arrow, bar, rightwards.
The Wikipedia has the following information about this codepoint:
The tab keyTab ↹ (abbreviation of tabulator key or tabular key) on a keyboard is used to advance the cursor to the next tab stop.
