HTML2PDF support for japanese language(utf8) is not working

问题

For report generation in PHP I am using HTML2PDF.

It works fine with English language but not giving proper output for Japanese language.

How can I set utg8 character in hHTML2PDF library.

Is there a way to achieve this in HTML2PDF library. I am gettign output like "???????????????" instead of Japanese text

In /var/www/html/html2pdf/locale folder following files I found en.csv, fr.cvs, cs.csv, da.csv

Can we get such file for Japanese too.

Below is my code

<?php

$content = ob_get_clean();

// convert to PDF
require_once('Classes/library/html2pdf.class.php');
try {
    $html2pdf = new HTML2PDF('P', 'A4', 'en');
    $html2pdf->pdf->SetDisplayMode('fullpage');
//      $html2pdf->pdf->SetProtection(array('print'), 'spipu');
    $html2pdf->writeHTML($content, isset($_GET['vuehtml']));
    $filename = $filename .'_'.date('Ymd');
    $html2pdf->Output($filename.'.pdf','D');//,'D'
}
catch(HTML2PDF_exception $e) {
    echo $e;
    exit;
}

Try to use a specify fonts instead of the default, try this

<?php
    $html2pdf = new HTML2PDF('P', 'A4', 'en', true, 'UTF-8');
    $html2pdf->setDefaultFont('arialunicid0'); //add this line
    $html2pdf->pdf->SetDisplayMode('fullpage');
    $html2pdf->writeHTML($content, false);
    $html2pdf->Output('japan.pdf');
?>

For polish signs helped this line:

$html2pdf->setDefaultFont('arialunicid0'); //add this line

Look it in Word, for me Helvetica showed squares. After font change problem disapered.

I solved this issue with this function:

$tpl_data = array_map('utf8_decode',$datas);

回答4:

Set encoding to UTF-8

 $html2pdf = new HTML2PDF('P', 'A4', 'en', true, 'UTF-8');

回答5:

$html2pdf = new HTML2PDF('P', 'A4', 'en', true, 'UTF-8', []);
$html2pdf->setDefaultFont('cid0jp'); //using this line
$html2pdf->writeHTML($html);
$html2pdf->pdf->SetTitle('PDFダウンロード');
$html2pdf->output('download.pdf');

I'm using this code and it working!
