U+21A8 Up Down Arrow with Base

U+21A8 was added in Unicode version 1.1 in 1993. It belongs to the block U+2190 para U+21FF Arrows in the U+0000 para U+FFFF Basic Multilingual Plane.

This character is a Otro símbolo 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+21A8 forms with similar adjacent characters prevents a line break inside it.

The CLDR project calls this character “flecha arriba abajo con base” for use in screen reading software. It assigns these additional labels, e.g. for search in emoji pickers: abajo, arriba, base, flecha.
