    I changed LaTeX to XeLaTeX, and this time I did not get any error
messages, but
the character remained undisplayed.
   Upon reading the .log file however, I found a piece of advice reading
"You must be using
an old version of ucs. Please replace \usepackage[utf8]{inputenc} with
\usepackage[utf8x]{inputenc} in your preamble".

  This I did, but the return symbol still won't appear on the PDF.
