U+1F1FE "🇾" Regional Indicator Symbol Letter Y Unicode Character

U+1F1FE "🇾" Regional Indicator Symbol Letter Y is a codepoint within a special range designated to represent individual alphabetical letters used exclusively for creating regional flag emojis. When combined with another regional indicator symbol letter, such as the Letter X, the pair forms a two character sequence that renders as the flag of a specific country or region, following the ISO 3166 1 alpha 2 standard. On its own, this character appears as a stylized letter "Y" inside a square box, but its purpose is never to be used alone; it is strictly a building block for software to display a national flag emoji.
