Regional Indicator Symbol Letter U (U+1F1FA) is one of the 26 regional indicator symbols used to build country flag emojis. It is not meant to stand alone; instead, it is combined with a second regional indicator to form an emoji flag sequence that corresponds to an ISO 3166-1 alpha-2 country code. Examples include U+1F1FA U+1F1F8 for the United States (US), U+1F1FA U+1F1E6 for Ukraine (UA), and U+1F1FA U+1F1FF for Uzbekistan (UZ). When a valid pair is recognized, platforms typically render the two characters as a single flag glyph.
By itself, this character may display as a letter βUβ inside a square or rounded rectangle, or it may appear as a missing-glyph box if the font or platform lacks support. On Apple/iOS and most modern systems, a single regional indicator shows visibly as a boxed letter, but it does not function as a standalone emoji. It does not modify other emojis, does not use a zero width joiner, and does not take skin-tone modifiers; its role is strictly to compose flags through pairing with another regional indicator. Ordering matters: U followed by S makes the US flag, while an unsupported or non-assigned pair typically remains two separate regional indicator symbols. Note that regional indicators are distinct from flag tag sequences (which use the black flag plus tag characters for entities like the UN or subregions); Letter U participates only in the two-letter country mechanism.
The letter U is represented using a Unicode regional indicator symbol.
