如何在codeigniter中使用bangla语言生成pdf文件

Question

我正在使用m_pdf为英语工作，但没有使用孟加拉语。我已加载m_pdf库

请帮助任何人

这是我的控制器代码：

public function download_pdf(){
    $sess_info = $this->session->userdata('loggin_user');
    $user_name = $sess_info->user_name;
    $profile_id = $this->uri->segment(3);
    $data = [];
    //load the view and saved it into $html variable
    $data['get_profile']=$this->Dashboard_model->get_profile($profile_id);
    $html=$this->load->view('users/profile_pdf', $data, true);
    //this the the PDF filename that user will get to download
    $pdfFilePath = $user_name.".pdf";
    $this->m_pdf->pdf->WriteHTML($html);
    $this->m_pdf->pdf->Output($pdfFilePath, "D");   
}

Answer 1

在将任何数据放入PDF

之前设置UTF-8编码

$this->m_pdf->pdf->allow_charset_conversion = true;
$this->m_pdf->pdf->charset_in = 'UTF-8';

Answer 2

在你的ttf目录下载并添加kalpurush.ttf文件，然后在控制器中...

$mpdf = new \Mpdf\Mpdf([
      'default_font_size' => 16,
      'default_font' => 'kalpurush'
       ]);
$stylesheet = '<style>'.file_get_contents('assets/css/style2.css').'</style>';

$html = $this->load->view('print',[],true);
$mpdf->WriteHTML($stylesheet,1);
$mpdf->WriteHTML($html,2);
$mpdf->Output();
