My DD has a Safia in her class, pronounced Saf-ee-ya. She also has a girl called Saf-e-ya (much shorter e sound) but I'm not sure how that one is spelt. There's a Sophie and a Sophia in her year group, must've been popular that year!
I think it sounds quite a nice name, though I haven't heard it before. But I think that there will be a need for endless explanations about spelling and pronunciation. But there is nothing strange about it at all.
my first thought is that it's the name of the beautiful woman whom Elias Cole marries after he helps the authorities to do away with her first husband Julius in Aminatta Forna's amazing novel "The Memory of Love" but I doubt many people will have read that novel
