Summary0015463: Call to iconv() doesn't fail gracefully and prevents FCKeditor from loading
DescriptionSeveral users reported that FCKeditor failed to load when opening the 'Send a Message' page. The problematic code was found in send_core.php around line 1032 and includes a call to iconv, which does not seem fail gracefully, and apparently prevents FCKeditor from loading.

The issue occurred on systems that do NOT have the iconv module included in their PHP installation.

A possible solution is to add a fall back method in case iconv isn't detected, though I'm not sure if using iconv in the first place is a very good idea, given that it apparently is a non-standard PHP extension.
Steps To ReproduceSystem details available in this forum thread: http://forums.phplist.com/viewtopic.php?p=74819#p74819
Additional Informationbpbeinlich found the problematic code section:

OK, here's the culprit:

This block of code appears in send_core.php beginning at line 1032:

$utf8_subject = $subject;
$utf8_from = $from;
if (strcasecmp($GLOBALS['strCharSet'], 'utf-8') <> 0) {
$utf8_subject = iconv($GLOBALS['strCharSet'],'UTF-8',$utf8_subject);
$utf8_from = iconv($GLOBALS['strCharSet'],'UTF-8',$utf8_from);
}

The first call to iconv crashes the page. I looked deeper and discovered that these variables ($utf8_subject and $utf_from) are not used anywhere. So this code is apparently not used at all. I commented out the entire block of 6 lines and the page now displays correctly.

bpbeinlich' observation that the $utf8_subject and $utf8_from variables aren't used seems to be correct. Assuming they were to be used in the code changes suggested by lwc in issue 15324, then the changes seem to be incomplete and would probably need to look like this:

  $scheduling_content = '<table>';
// custom code - start
  $utf8_subject = $subject;
  $utf8_from = $from;
  if (strcasecmp($GLOBALS['strCharSet'], 'utf-8') <> 0) {
     $utf8_subject = iconv($GLOBALS['strCharSet'],'UTF-8',$utf8_subject);
     $utf8_from = iconv($GLOBALS['strCharSet'],'UTF-8',$utf8_from);
  }

  $maincontent .= '
  <tr><td>'.Help("subject").' '.$GLOBALS['I18N']->get("Subject").':</td>
    <td><input type=text name="msgsubject"
    value="'.htmlentities($utf8_subject,ENT_QUOTES,'UTF-8').'" size=40></td></tr>
  <tr>
    <td colspan=2>
    </td></tr>
  <tr><td>'.Help("from").' '.$GLOBALS['I18N']->get("fromline").':</td>
    <td><input type=text name=from
    value="'.htmlentities($utf8_from,ENT_QUOTES,'UTF-8').'" size=40></td></tr>
  <tr><td colspan=2>

  </td></tr>';
// custom code - end

A fall back method would still need to be added for systems that do not have the iconv extension, if you decide keep using iconv.
