They are a lot of way to replace two input chars by two others. My editor (winedt) can do it in the background without any problems when saving and restoring a file. But this doesn't solve the problem that you don't want to replace every occurrence of the two chars but only some - and that there isn't a rule/regex or something like that to discern the one from the other. What you would need is a primitive command or a callback which allows to extend the list of units which can be used with \vskip etc. As long as this doesn't exist you will have to mark one of the sets somehow. -- Ulrike Fischer -------------------------------------------------- Subscriptions, Archive, and List information, etc.: http://tug.org/mailman/listinfo/xetex
