Regional Indicator

Unicode Version 18.0

Regional Indicator is a character property that defines a set of 26 letters, from U+1F1E6 to U+1F1FF, specifically used to represent country flags in emoji sequences. Each indicator corresponds to a single letter of the Latin alphabet, from A to Z. When two regional indicators are placed consecutively, they combine to form a single flag emoji, such as 🇺🇸 for the United States or 🇯🇵 for Japan. The property also affects text segmentation and rendering, ensuring that each indicator is treated as a separate grapheme unless paired correctly. While these characters are technically letters, they have no standalone meaning in plain text, and their use is strictly reserved for flag representation. This mechanism allows for dynamic flag support without encoding every national flag as a unique character.
