Incorrect output of font

[dnznk]

Describe the bug First of all, I know this is only a wrapper, but it seems to me that dompdf is working. Sometimes the content of the generated PDF is Japanese. Just like for many others before me the PDF shows either only question marks or boxes, hence can't display the special characters.

To Reproduce Steps to reproduce the behavior:

• "laravel/framework": "^7.0", "barryvdh/laravel-dompdf": "^2.0",
• return Pdf::loadView('pdfs.explo', $data)->stream($pdfName . '.pdf');
• Characters that won't display: スペア パーツ [example]
• Already tried to use DejaVu Sans (shows boxes) and also NotoSans (donwloaded and added to storage, aswell as implemented with @font-face)
• 'convert_entities' => true, set to false
• If I change the output not to show a rendered PDF but a html page, everything is displayed correctly.

Expected behavior The Japanese characters (same problem for Greek) should be displayed in the rendered PDF.
