Tcpdf Utf-8 Symbols Not Showing Up

TCPDF UTF-8 symbols not showing up

Set the $unicode parameter on the TCPDF constructor to false and the $encoding parameter to 'ISO-8859-1' or some other character map.

This will help you:

Default for UTF-8 unicode:

$pdf = new TCPDF(PDF_PAGE_ORIENTATION, PDF_UNIT, PDF_PAGE_FORMAT, true, 'UTF-8', false);

Example of constructor for European charset:

$pdf = new TCPDF(PDF_PAGE_ORIENTATION, PDF_UNIT, PDF_PAGE_FORMAT, false, 'ISO-8859-1', false);

TCPDF UTF-8 Japanese File Name Not Showing up

I resolved this.

In 'tcpdf.php' file: i was comment from line 7559 to 7562

public function Output($name='doc.pdf', $dest='I') {
    ...
    //if ($dest[0] != 'F') {
        //$name = preg_replace('/[\s]+/', '_', $name);
        //$name = preg_replace('/[^a-zA-Z0-9_\.-]/', '', $name);
    //}
    ...
}

TCPDF is not showing Unicode from MySQL database

I have solved my issue using mPDF. It's quite easy to use compared to TCPDF.

TCPDF HTML with Special Characters displays empty PDF file

before line $pdf->writeHTML

$html = utf8_decode($html);

maybe

$html = utf8_encode($html);
