title: Double encoding issue with perl/cgi and mysql
body: <p>I switched an self developed Web-Application based on Perl/CGI and MySQL from one server to another and since then, special characters from database content like german umlauts are shown as black diamond with question mark. Everything else, even text with umlauts which is coming from the script is ok. After lot of research I have still no clue what might cause the issue.</p>
  
  <p>The original server is openSuSE 13.1 with Perl 5.18.1 and MySQL 5.6.25 while the new server is Debian 8 with Perl 5.20.2 and MySQL 5.5.44. I transfered all files with zipped tar files and configured MySQL and Apache identically, i.e. setting utf-8 and so on. After dumping and restoring sql data I was able to verify that data in new MySQL is fine.</p>
  
  <p>I tried many things so far, playing around with use Encode and use utf8 in Perl, setting DBI with utf8 but nothing helps. Feel quite lost now, so any hint is appreciated. Let me know if more info is necessary.</p>
  
  <p>Kind regards,
  Uwe</p>
