ofn-paths-to-selection does it for paths. But what you have is a jumble of strokes. Hence my suggestion to see if OTAP works well enough with your font since you can make it produce one path per character.
One solution (the solution?) to your problem is to have oriented strokes, where for instance clockwise strokes select the inside and counter-clockwise strokes select the outside (so the two strokes of an "O" would be opposite for instance). Then the final selection is the union of all the selections from CW strokes intersected with the union of all the selections from the CCW strokes. But this requires strokes to be closed, have no loops; and makes hand-made paths harder to use because you now need to be able to control the direction of a stroke.
