I don't know either. The traditional response in such a situation is "implement it and submit a patch". But I don't think that there is a forumula in the weight one case (as there is in higher weights) so it will not be easy. See http://magma.maths.usyd.edu.au/magma/handbook/text/1528 for what Magma does. I am not an expert on this, but I think that it is not at all easy.
