GOST 16876-71 (Russian: ГОСТ 16876-71) is a romanization system (for transliteration of Russian Cyrillic alphabet texts into the Latin alphabet) devised by the National Administration for Geodesy and Cartography of the Soviet Union.
GOST was an international standard so it included provision for a number of the languages of the Soviet Union.
UN system relies on diacritics to compensate for non-Russian Cyrillic alphabets.
The letters і, ѳ, ѣ, ѵ are found in texts from before the Russian orthographic reform of 1918.
During 1995—2009 the Ukrainian Derzhstandart tried to introduce the new system of transliteration instead of the Soviet one, though none of the draft projects were accepted officially.
