In my Magento store, I am facing one issue that I am not able to import the product with special characters. For the CSV base I have followed the below tutorial. Can anyone please help me how can I encode with UTF-8 in CSV when writing it?


Note: It's custom product import

You can convert your string to UTF-8 by using default PHP function.

mb_convert_encoding(string, encode_type)

Please check below example for more details.

$products[] = array(1,'Test 1','test 1',100);
$products[] = array(2,'Test 2','test 2',299);

foreach ($products as $item) {
     $itemData = [];
     $itemData[] = mb_convert_encoding($item[0], "UTF-8");
     $itemData[] = mb_convert_encoding($item[1], "UTF-8");
     $itemData[] = mb_convert_encoding($item[2], "UTF-8");
     $itemData[] = mb_convert_encoding($item[3], "UTF-8");

I hope this will help you.


Please follow the below code snippets,

        //Declare column and data
        $result[] = [
        $result[] = [
        $varDir = $this->_filesystem->getDirectoryRead(DirectoryList::VAR_DIR)->getAbsolutePath();
        $directory = $this->_filesystem->getDirectoryWrite(DirectoryList::VAR_DIR);
        $tmpFolder = 'customfolder';

        $filename = "filename" . ".csv";
        if ($this->_file->isExists($varDir . $tmpFolder . DIRECTORY_SEPARATOR . $filename)) {
            $this->_file->deleteFile($varDir . $tmpFolder . DIRECTORY_SEPARATOR . $filename);

        $filePath = $varDir . $tmpFolder . DIRECTORY_SEPARATOR . $filename;


and add dependency to your constructor,

        use Magento\Framework\Filesystem;
        use Magento\Framework\App\Filesystem\DirectoryList;
        use Magento\Framework\Filesystem\Driver\File;
        use Magento\Framework\File\Csv;
