Supported Regions

V16 uses per-country character sets — pass a 2-letter country code (e.g. de, au, ru) for best accuracy, or a group code (eu, asia, eup, na, univ, etc.).

Supports 80+ countries across 12 regional groups: EU (37), Ex-USSR (15), Asia (17), N. America (3), S. America (2), Africa (2), Oceania (2), UK (4), China, Korea, Japan.

Unknown regions fall back to univ with a warning.

See Full Region & Country Reference for the complete table with all country codes and flags.
