MPDF should support this according to the logs: Set /Lang entry for better accessibility when document language is available (@cuongmits, Set the default language using /Lang entry #1418)
When adding html lang attribute , MPDF is not picking up on this and setting it accordingly.
More info on default lang: https://www.w3.org/WAI/WCAG22/Techniques/pdf/PDF16
I tried code below but language is still not set:
$html = '<!DOCTYPE html><html lang="en-CA"><head><title>'.$doc_title.'</title><style>body{font-size: 12px;}h1{font-size: 14px}.red-asterisk{color:#cf1818;margin-left:4px;}.underline{border-bottom:2px solid;}.list-no-style{list-style:none;}ul{padding-top:30px;}ul ul{padding-top:0;}li{padding-top:10px;}</style></head><body>' . $prepared_checklist_html . '</body></html>';
$mpdf = new \Mpdf\Mpdf(
array(
/*
'default_font' => 'arial', */
'default_font_size' => 12,
'currentLang' => 'en-CA',
'default_lang' => 'en-CA',
'tempDir' => $new_child_directory,
)
)
$mpdf->curlTimeout = 10;
$mpdf->simpleTables = true;
$mpdf->SetCompression( true );
$mpdf->PDFA = true;
$mpdf->PDFAauto = true;
$mpdf->SetDisplayMode( 'fullwidth' );
$mpdf->SetTitle( 'Plan Checklist' );
$mpdf->SetDisplayPreferences('DisplayDocTitle');
Thank you KIKO!
While I did not use 'autoScriptToLang to true' your suggestion of following the trail led me to this link specifically example2 where I found
https://mpdf.github.io/reference/mpdf-functions/construct.html#example-2
So I added the line to my existing instance of MPDF and the PDF document language is now set correctly.
