This character is a Other Symbol and is commonly used, that is, in no specific script. The character is also known as military term, battleground (on maps) and killed in action.
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+2694 forms with similar adjacent characters prevents a line break inside it.
The CLDR project calls this character “crossed swords” for use in screen reading software. It assigns these additional labels, e.g. for search in emoji pickers: crossed, swords, weapon.
This character is designated as an emoji. It will be rendered as monochrome character on conforming platforms. To enable colorful emoji display, you can combine it with Variation Selector-16: ⚔️ See the Emojipedia for more details on this character’s emoji properties.
