Dompdf does not support fallback fonts, so you can't use your favorite font if it does not support your characters, and you also can't set another font to be the fallback font for those characters like droid sans fallback.

What you can do instead is take advantage of regex unicode script ranges: https://www.regular-expressions.info/unicode.html to wrap those blocks of text into spans and give them the fallback font.

Example:

$body = 'test 简化字 彝語/彝语 test číslo € černý Češký';

$cjk_scripts = 'Bopomofo|Han|Hiragana|Katakana';
$cjk_scripts = preg_replace('/[a-zA-Z_]+/', '\\p{$0}', $cjk_scripts);

// wrap the CJK characters into a span with it's own font
$body = preg_replace("/($cjk_scripts)+/isu", '$0', $body);

// a font that supports CJK characters
$cjk_font_path = APP_PATH.'/fonts/DroidSansFallbackFull.ttf';

$html = <<





$body

HTML;

$dompdf = new \DOMPDF();
$dompdf->set_paper('A4');
$dompdf->load_html($html);
$dompdf->render();

$dompdf->stream('test.pdf', ['Attachment'=>0]);
