U+017D, Russian (GOST) and English (both BSI and ALA) transliteration: /zh/, e.g. М. М. Жванецкий = M. M. Zhvanetsky (popular Soviet and contemporary Russian satirist and stand-up comedian artist).
In combination with д - /d/, this letter transcribes the English letters /j/ and /g/ (if followed by /e/ or /i/), e.g. Джон = John, Джордж = George.
Likewise, it is used to transcribe the French /j/, e.g. Жанна д\'Арк = Jeanne d\'Arc.
Similarly, this letter in Russian is used in English and French foreign and loan words, e.g. джаз = jazz, журнал = journal.
