Why Do Flags Look Like Two Letters on Windows?
On Microsoft Windows (including Windows 10 and Windows 11), the default system font Segoe UI Emoji intentionally does not render national flag graphics, displaying two-letter regional indicator symbols (such as US, GB, or IN) instead. When you copy a flag from GeneratorFont and paste it into Instagram, Twitter, Discord, WhatsApp, iPhone, Android, or Mac, it displays as the full, vibrant national flag!
How Flag Emojis Work in Unicode
Flag emojis are composed of two Unicode Regional Indicator Symbols (from U+1F1E6 for 'A' to U+1F1FF for 'Z') corresponding to the official ISO 3166-1 alpha-2 country code. For example, the Regional Indicator Symbol Letter U (๐บ) followed by S (๐ธ) creates the United States flag emoji ๐บ๐ธ.
