I've an issue with email notifications sent from the server in that the content has some characters replace by '=' if the email client used is Microsoft based, e.g. Outlook, Hotmail. The following approaches have not helped solve the issue
Setting newline in the tools_communicate.php file
$this->email->set_newline( "\r\n" );
updating config.php to include
$config['email_newline'] = "\r\n";
defining different charsets in the head meta tags
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
Any suggestions appreciated, Thanks!
