Some character names in the Russian localisation don't conform to the Russian orthographic transcription rules and tradition:
Arica. Current variant: Арика. Correct variant: Арица.
Cveta. Current: Света. Correct: Цвета. Note: Света is a diminutive form of the Russian name Светлана (Svetlana) which is absolutely unrelated to the name Cveta.
Marin. Current: Мэйрин. Correct: Марин.
Pavle. Current: Павло. Correct: Павле.
