Hello great plugin.
Please remove the utf8 conversion it is not needed.
ip11166 perhaps had his database and or database tables in ansi and not utf8.
What happens now is that if the database tables are in utf8 then you get ????? characters for non english.
I commented out the line
echo iconv("UTF-8", "ISO-8859-1//TRANSLIT", $exports)
and added
echo $exports
and works fine.
Thanks
