Not latin data export patch

If you want to use not latin characters and export them to csv. You may use the patch below.

Open and edit file visdata.php function export() and line
$unicode_str_for_Excel = iconv("UTF-8", "windows-1250",$row->$prop);
change it to
$unicode_str_for_Excel = $row->$prop;

If you have the same problem with Labels change
$unicode_str_for_Excel = iconv("UTF-8", "windows-1250",$rowField->label);
to
$unicode_str_for_Excel = $rowField->label;

Once again, I am really appreciate your work and I believe its a great offer to Joomla community.
