U+224C All Equal To

U+224C was added in Unicode version 1.1 in 1993. It belongs to the block U+2200 to U+22FF Mathematical Operators in the U+0000 to U+FFFF Basic Multilingual Plane.

This character is a Math 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 mirrored into Glyph for U+2245 Approximately Equal To. If its East Asian Width is “narrow”, U+224C 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 “wszystkie równe” for use in screen reading software.

Wikipedia ma następujące informacje na temat tej współrzędnej kodowej:

The equals sign (British English) or equal sign (American English), also known as the equality sign, is the mathematical symbol =, which is used to indicate equality in some well-defined sense. In an equation, it is placed between two expressions that have the same value, or for which one studies the conditions under which they have the same value.

In Unicode and ASCII, it has the code point U+003D. It was invented in 1557 by Robert Recorde.
