The code for the \XeTeXgenerateactualtext feature (it's an integer parameter; set it to 1 to get ActualText added to the PDF, for better copy/paste and search in Acrobat) is now on sourceforge, in an "actualtext" branch, for anyone who wants to try building and experimenting with it.
Windows 32bit binary for tests based on Jonathan's 845506 is available in: http://members2.jcom.home.ne.jp/wt1357ak/xetex-ac-txt.zip
I'll remove the file in due time. Best, Akira -------------------------------------------------- Subscriptions, Archive, and List information, etc.: http://tug.org/mailman/listinfo/xetex
