Regional Indicator - Yes

Yes is the designation for characters that function as regional indicator symbols, which are the two-letter codes used to represent country flags in text. When two such characters appear consecutively, they combine into a single flag emoji, with the specific flag determined by the pair of letters, such as US for the United States or JP for Japan. This value ensures that these letterlike symbols are treated as distinct from ordinary Latin letters, allowing them to be recognized and displayed correctly as flag components across platforms, rather than being misinterpreted as regular text or spaces.
