Thanks. Yes copying Unicode strings is a common practice and I use it for some of the scripts I am writing about. I am busy with a write-up that spans almost all known scripts, for some scripts macros work better for me as I can type \LE{180} and get the glyph No. 180 and \LE[2]{180} to get variant 2 etc., and the star version \LE*{..} can do something else.
