CSV import and export feature request
Sorry for the delay, you can set the charset for CSV Import in the plugin with this line :
'ENCODING' => 'CP1252', // CP1252, ASCII, ISO-8859-1, UTF-8 - More: http://php.net/manual/en/mbstring.supported-encodings.php
And for CSV Export I believe it should export at UTF-8.
But if either of those aren't working for you or are still an issue let me know and we'll get someone on it.
