The regional indicator symbols are a set of 26 alphabetic Unicode characters (A–Z) intended to be used to encode ISO 3166-1 alpha-2 two-letter country codes in a way that allows optional special treatment.

A pair of regional indicator symbols is referred to as an emoji flag sequence (although it represents a specific region, not a specific flag for that region).
