Variation Selectors
The Variation Selectors block is a block of the Unicode standard that contains characters that are used to specify a specific variation of a character from another Unicode block. These characters are called variation selectors, and are typically used to represent characters with multiple possible forms or appearances, such as characters with different colors or styles. The characters in this block are not used to represent text on their own, but are instead used in combination with characters from other Unicode blocks to specify a specific variation of that character. The Variation Selectors block is often used in conjunction with other Unicode blocks to represent text in digital form.
