Unisex names are common and acceptable in Israel. The meaning of Lior is suitable for both genders. Liora, however, would be strictly feminine. People in Western cultures, however, often feel uncomfortable with this concept and MUST associate names with a particular gender. In Germany and Argentina, for example, the naming laws prohibit names that don't specify a particular gender. In Israel, this unisex trend became common 20 or so years ago when people were pushing for gender equality. However, it is now becoming less common as people have realized that this leads to confusion. Nevertheless, I think Lior is perfectly fine for a boy or a girl.
