I wish I could buy a FontLab licence later on but ATM, I try to learn and progress with Inkscape and FontForge. When I import SVG glyphs created with Inkscape they have a very bad aspect in FontForge since I used group/ungroup or "binary" (e.g. substract) of simple shapes (e.g. a black circle inside a white circle). All the shapes are displayed and I dont see ATM if I have to build the shapes without combinations or if there are solutions to make the SVG import inline with what is displayed by Inkscape.
