In the Japanese dub, Oscar is voiced by Rie Kugimiya, who is a woman, though she was the Japanese voice actor for Alphonse Elric, the younger brother of the protagonist Edward, in Fullmetal Alchemist. Oscar's English voice actor is Aaron Dismuke, who voiced Alphonse Elric in the English dub.

I know it's not too rare in western animation for women to voice act for young boy characters (see Tara Strong as Timmy Turner, in The Fairly OddParents), and I wouldn't be surprised if they do the same in the east.
