Thank you for this excellent advice.  I have encounted (apparently) 
identical problems attempt to process legacy LaTeX documents that use 
Silvio Levy's/Claudio Beccari's 8-bit polytonic Greek encoding. Are you 
in a position to advise which variant of \usepackage [latin1] {inputenc} 
/ \usepackage [latin9] {inputenc} / \usepackage [latin$n$] {inputenc} 
might best address this issue ?
