U+1F191 Squared Cl

U+1F191 was added in Unicode version 6.0 in 2010. It belongs to the block U+1F100 to U+1F1FF Enclosed Alphanumeric Supplement in the U+10000 to U+1FFFF Supplementary Multilingual Plane.

This character is a Other Symbol and is commonly used, that is, in no specific script. The character is also known as clear.

The glyph is not a composition. Its East Asian Width is wide. In bidirectional text it is written from left to right. When changing direction it is not mirrored. If its East Asian Width is “narrow”, U+1F191 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 “CL button” for use in screen reading software. It assigns these additional labels, e.g. for search in emoji pickers: button, CL.

This character is designated as an emoji. It will be rendered as colorful emoji on conforming platforms. To reduce it to a monochrome character, you can combine it with Variation Selector-15: 🆑︎ See the Emojipedia for more details on this character’s emoji properties.
