I adjusted the mark positioning lookup for my Arabic opentype font in VOLT. The shipped font works correctly in most applications in Mac, PC and ioS8 . However I discovered a case where problems occur: When exporting from Word 2013 to PDF the vertical mark positions are not adjusted at all, and they stay in their default positions. This does not occur in a font like Arial, as seen to the bottom of the illustration.
Any suggestions to solve this welcome
