ER — Eritrea

Eritrea is a Horn of Africa country along the Red Sea coast, independent from Ethiopia since 1993 after a 30-year war of independence. Asmara, the capital, is a UNESCO World Heritage Site known for its remarkably preserved Art Deco and modernist architecture built during Italian colonial rule. The Eritrean Nakfa (ERN) is named after the town of Nakfa, a symbol of the independence struggle. For developers, the ER country code maps to ti-ER for Tigrinya (written in Ge'ez/Ethiopic script), ar-ER for Arabic, and en-ER for English. Ge'ez script support requires specific font and rendering capabilities, as the script uses syllabic characters rather than an alphabet. The .er domain and +291 calling code serve Eritrean digital infrastructure. Eritrea's unique writing system and multiple official languages make it an important edge case for testing script rendering and input method support in internationalized applications.
