U+1F1E6 "🇦" Regional Indicator Symbol Letter A Unicode Character

U+1F1E6 "🇦" Regional Indicator Symbol Letter A is a special character used in sequences to represent national flags, as it is not intended to be displayed alone but rather paired with another regional indicator letter to form a two letter country code. For example, when combined with U+1F1E7 "🇧", it creates the flag for Antigua and Barbuda. This character belongs to the Enclosed Alphanumeric Supplement block and is encoded for compatibility with the ISO 3166 1 alpha 2 standard, allowing a text based representation of regional identifiers without needing dedicated emoji flag glyphs for every territory.
