I think I've asked something like this before, but I can't find the thread and I don't think I got a answer last time.
Is it possible to copy metrics from one font to another so that the side bearings are copied. If I export the metrics from one font and then import them into another font, it's the width and the left sidebearing that are copied.
It's my own metrics I'm trying to copy from an earlier version of a font to a later version where some of the glyphs widths have changed but I still wanted to keep the the old side bearings. Back in Fontographer days it was possible to copy the metrics and you could choose if you wanted to copy the width or sidebearing - is this the case with FL.
