U+21A1 Downwards Two Headed Arrow

U+21A1 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. El carácter es también conocido como form feed y fast cursor down.

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+21A1 forms with similar adjacent characters prevents a line break inside it. The glyph can be confused with one other glyph.

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

El Wikipedia tiene la siguiente información acerca de este punto de código:

A page break is a marker in an electronic document that tells the document interpreter that the content which follows is part of a new page. A page break causes a form feed to be sent to the printer during spooling of the document to the printer. Thus it is one of the elements that contributes to pagination.
