Why doesn't PDFtk display Cyrillic when filling out PDF forms?

Question

PHP

I need to fill PDF forms with data using PHP. I'm using the mikeheartl library as a wrapper for PDFtk, but PDFtk doesn't display my data in Russian when I turn off file editing with the flatten() function.

How can I fix or work around this issue. The HTML to PDF option is not suitable.

Here is the file generation method:

private function generate($fields, $filename, $path)
    {
        $options = array(
            'command' => "C:\Program Files (x86)\PDFtk\bin\pdftk.exe",
            'useExec' => true,
        );

        $pdf = new Pdf($path, $options );
        $res = $pdf->fillForm($fields)
        ->flatten() // Отключает редактирование
        ->compress()
        ->needAppearances() 
        ->saveAs("./completed/" . $filename);

        if($res === false) {
            print_r($pdf->getError());
            return false;
        }

        return $filename;
    }

1. Try adding this to your function, or else change UTF-8 to WINDOWS-1251 later. 2.
'encoding' => 'UTF-8', // option with argument

'commandOptions' => array(
        'useExec' => true,      // Can help on Windows systems
        'procEnv' => array(
            // Check the output of 'locale -a' on your system to find supported languages
            'LANG' => 'en_US.utf-8',
        ),
    ),

Try changing the language to ru_RU.utf-8 or ru_RU.win-1251 or ru_RU.windows-1251
