U+0040 was added in Unicode version 1.1 in 1993. It belongs to the block U+0000 to U+007F Basic Latin in the U+0000 to U+FFFF Basic Multilingual Plane.

This character is a Other Punctuation and is commonly used, that is, in no specific script. Znak jest również znany jako at sign i arroba (old Spanish unit of weight).

The glyph is not a composition. Its East Asian Width is narrow. In bidirectional text it acts as Other Neutral. When changing direction it is not mirrored. The word that U+0040 forms with similar adjacent characters prevents a line break inside it.

The CLDR project calls this character “znak małpy” for use in screen reading software. It assigns these additional labels, e.g. for search in emoji pickers: małpa, symbol małpy.

Wikipedia ma następujące informacje na temat tej współrzędnej kodowej:

@ (małpa) – znak pisarski, wykorzystywany głównie w adresach poczty elektronicznej oraz jako identyfikator (handle) użytkownika na mikroblogach takich jak Twitter czy Instagram. Znak pochodzi z łacińskiej ligatury zastępującej w średniowiecznych i renesansowych rękopisach handlowych słowo „ad” (do, przy) i oznaczające m.in. odbiorcę przesyłki. W języku angielskim czytany jest „at” (przyimek oznaczający „w”, „przy” albo „po [jakiejś cenie]”) i stosowany jest niekiedy w księgowości do oznaczania cen.
