IT WORKED! Now all the little smileys, arrows, etc. show up in my final HTML output. Much thanks for the tip. I just put my final html content file through your encode process before outputting to web:
$pagecontent = encode('ascii', $pagecontent, FB_HTMLCREF);

p.s. for anyone reading this later: If you store your JSON data in a file, then you need to access it explicitly as utf8:
open(my $fh, '<:utf8', $filename)
I had to do this and use Anonymous Monk's FB_HTMLCREF process to finally get the emoticons to show.

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post, it's "PerlMonks-approved HTML":


  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
