U+1F1FD "🇽" Regional Indicator Symbol Letter X Unicode Character

U+1F1FD "🇽" Regional Indicator Symbol Letter X is part of a special set of 26 characters representing the letters A through Z, designed specifically for creating regional flag emojis. When combined with another regional indicator letter, it forms a two-letter country code that renders as a single national flag emoji, such as when paired with U+1F1F2 (Regional Indicator Symbol Letter R) to produce the flag of Mexico (🇲🇽). By itself, this character is invisible in most text contexts and is not intended to stand alone as a meaningful symbol, serving instead as a building block for flag representations.
