I have found a bug when exporting an indd to idml. If a a carriage return falls in a character count that is a multiple of 8000 + 1 it is converted to a paragraph separator (u2029). I am in the process of mass exporting around 3000 files to idml for a project. I am trying to come up with a way with a script to check the files to see if carriage returns exist in these locations. I am fairly new to scripting and don't know how this would be done. I know it is possible to get character counts but is it possible to check if a character exists in a certain character count from the beginning of a story? Any help on this would be appreciated.
Also has anyone else ran into this with exporting to idml? I have submitted a bug report. This is can be recreated across multiple computers, OS's and versions of InDesign.
