Regarding my previous post, I just found that the rotatebox command can bear quite a bit of self-embedding, and I have come up with the following temporary kluge. It's ugly, but it works with microtype nicely, avoiding the use of RotatedGlyphs. Half spaces are added for horizontal and vertical adjustment.
{\fontspec{SBL Hebrew} \raisebox{6mm}{% \rotatebox{-90}{% \rotatebox{90}{\,י}% \rotatebox{90}{ה}\,% \rotatebox{90}{\,ו}\,% \rotatebox{90}{ה} }}} Cheers, Juan -------------------------------------------------- Subscriptions, Archive, and List information, etc.: http://tug.org/mailman/listinfo/xetex
