TR — Turkey

Turkey is a transcontinental country spanning Europe and Asia, with Istanbul straddling the Bosphorus. Ankara is the capital, while Istanbul is the largest city and economic center. Turkey has a large, young population and a growing technology sector. The country officially changed its international name to 'Türkiye' in 2022. The Turkish Lira (TRY) uses the ₺ symbol. For developers, the TR country code maps to the tr-TR locale for Turkish. The .tr domain and +90 calling code serve Turkey. The 2022 name change from Turkey to Türkiye requires Unicode support for the ü character in country name databases. Turkish has specific case conversion rules — the lowercase of 'I' is 'ı' (dotless i), and the uppercase of 'i' is 'İ' (dotted I) — this is one of the most famous locale-specific casing bugs in programming. The TRY currency code is newer (replaced TRL after redenomination). Turkey's large tech ecosystem, centered in Istanbul, and its massive domestic market make tr-TR localization essential.
