PHP - 韩语字符未使用UTF-8进行转换

Question

我通过在图像上附加名称来生成图像，但韩文文字显示不正确。

我尝试在html上添加<meta http-equiv="content-type" content="text/html; charset=UTF-8" />，但无法查看준석 김

的实际文字

我有以下函数，我用ajax调用生成图像。

public function CreateMyCertificate()
    {
        if (Auth::check()) {
            $MyScratchProjects = new MyScratchProjects();

            if(ctype_digit($_POST['id'])) {
                if(isset($_POST['id']) && !empty($_POST['id'])) {
                    $DiplomaIdx = $_POST['id'];
                } else {
                    $DiplomaIdx = "0";
                }

                $GetMyDiploma = $MyScratchProjects->GetMyDiploma($DiplomaIdx);

                $CertificatePath = url().'/public/upload/diplomas/certificate/'.$GetMyDiploma[0]->CertificateTemplate; // Get certificate
                $FileExt = pathinfo($CertificatePath, PATHINFO_EXTENSION);
                $Name = $GetMyDiploma[0]->FirstName.' '.$GetMyDiploma[0]->LastName; // Get user first & last name
                $CertificateName = strtolower($GetMyDiploma[0]->Title).'-certificate'; // Get user first & last name
                //$Name = "Wonkyu Kim";
                $SourceFile = $CertificatePath;

                //Set the Content Type
                //header('Content-type: image/jpeg');

                // Copy and resample the imag
                list($Width, $Height) = getimagesize($SourceFile);
                $ImageP = imagecreatetruecolor($Width, $Height);
                if (strtolower($FileExt) == 'png') {
                    $Image = imagecreatefrompng($SourceFile);
                } else if(strtolower($FileExt) == 'jpeg') {
                    $Image = imagecreatefromjpeg($SourceFile);
                } else if(strtolower($FileExt) == 'gif') {

                } else {
                    $Image = imagecreatefromjpeg($SourceFile);

                imagecopyresampled($ImageP, $Image, 0, 0, 0, 0, $Width, $Height, $Width, $Height);

                // Prepare font size and colors
                $TextColor = imagecolorallocate($ImageP, 129, 112, 167);
                $BgColor = imagecolorallocate($ImageP, 129, 112, 167);
                $Font = 'resources/assets/front/fonts/Roboto-Bold-webfont.ttf';
                $FontSize = 27;

                // Set the offset x and y for the text position
                $OffsetX = 0;
                $offsetY = 20;

                // Get the size of the text area
                $Dims = imagettfbbox($FontSize, 0, $Font, $Name);
                $TextWidth = $Dims[4] - $Dims[6] + $OffsetX;
                $TextHeight = $Dims[3] - $Dims[5] + $offsetY;

                // Add text
                //imagettftext($ImageP, $FontSize, 0, $OffsetX, $offsetY, $TextColor, $Font, $text);
                imagettftext($ImageP, $FontSize, 0, 270, 215, $TextColor, $Font, $Name);

                // Save the picture
