I am trying to create a pdf in the Tamil language, but I am experiencing font rendering issues. When I use the Baamini font, it works, but there is no English font in Baamini, so I tried other fonts such as latha.ttf, notosans.ttf, azaghi.ttf, and others, but these fonts do not work in tcpdf or fpdf. Please assist us in resolving this, and thank you in advance!
<?php
header('Content-type: text/html; charset=UTF-8') ;//chrome
require_once('tcpdf_include.php');
// create new PDF document
$pdf = new TCPDF(PDF_PAGE_ORIENTATION, PDF_UNIT, PDF_PAGE_FORMAT, true, 'UTF-8', false);
$pdf->setFontSubsetting(true);
$pdf->SetFont('freeserif', '', 12);
$pdf->AddPage();
$utf8text = '<html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"/> </head> <body> <p>தினமும் உங்களை இந்த தோட்டத்து வழியாக செல்லும்போது என்னை கவனிப்பீர்களா என்று திரும்பி திரும்பி பார்த்து செல்வேன். ஆனால் நீங்களோ வெறி பிடித்தது போல் மண்ணை கொத்தி கொண்டிருப்பீர்கள்.</p></body></html>';
$pdf->writeHTML($utf8text, true, 0, true, true);
$pdf->Output('example_067.pdf', 'I');
?>
My Output is
The damage is usually done when PDF inputs are parsed as UTF-8
We can see the graphics visuals are like 16 but underneath the text for search and extract is more like UTF-8
Now I can't say what's affecting you own sample as unseen but to use two languages you need more than one type of font, or more precisely, more than one font type. And those characters that are unconventional will actually be there but NOT as conventional text.
When you do that then we can expect that any well designed extractor will see both font types and convert the output to UTF-8 (Which is not normally a PDF internal font type)
