I imported a UFO file today and all glyphs were in random order in the Font view. One letter, followed by another letter in some other script, followed by a mark, followed by another letter, etc., in consecutive lines. The worst part was that some glyphs seemed inaccessible. Even though there looked fine in Font view, when I tried to edit them in a new tab the tab was empty. Trying to add them with cmd+F also had no result. There is not glyphorder parameter btw.
