How can I set encoding for export csv with Laravel Excel in Laravel

I using Laravel Excel for export CSV file in Laravel. How can I set the encoding for export csv file.

I have tried several ways:

1. Change config in excel.php

   'use_bom' => false,

2. Use mb_convert_encoding to convert content to before export.

   $exportData = mb_convert_encoding($exportData, "SJIS", "UTF-8");
   $pblClassExport = new \App\Exports\PblClassExport($exportData, 'test.csv');

But it's not working. The encoding of csv file auto change by file content :( I hope get your help. Thank you so much!
