U+25E4 Black Upper Left Triangle
U+25E4 was added in Unicode version 1.1 in 1993. It belongs to the block Geometric Shapes in the Basic Multilingual Plane.
This character is a Other Symbol and is commonly used, that is, in no specific script.
The glyph is not a composition. Its width in East Asian texts is determined by its context. It can be displayed wide or narrow. In bidirectional text it acts as Other Neutral. When changing direction it is not mirrored. If its East Asian Width is “narrow”, U+25E4 forms a word with similar characters, which prevents a line break inside it. Otherwise it allows line breaks around it, except in some numeric contexts.
The CLDR project calls this character “filled upper left triangle” for use in screen reading software. It assigns these additional labels, e.g. for search in emoji pickers: filled, left, triangle, upper.
The Wikipedia has the following information about this codepoint:
Geometric Shapes is a Unicode block of 96 symbols at code point range U+25A0–25FF.
