How to include Calibri font in tcpdf?

Question

PHP

Hello.
I can't figure out how to include the Calibri font in tcpdf?
Downloaded the Calibri.ttf file. I put it in a directory.
I connect like this:

require_once($_SERVER["DOCUMENT_ROOT"].'/libs/tcpdf/tcpdf.php');
$pdf = new TCPDF('P', 'mm', 'A4', true, 'UTF-8', false);
$fontname = TCPDF_FONTS::addTTFfont('/libs/tcpdf/fonts/Calibri.ttf', 'TrueTypeUnicode', '', 32);
$pdf->SetFont('Calibri', '', 9);

I am getting an error:

TCPDF ERROR: Could not include font definition file: calibri

Please tell me what am I doing wrong? UTF-8 encoding.

Just forgot something:

$fontname = TCPDF_FONTS::addTTFfont($_SERVER['DOCUMENT_ROOT'] . '/libs/tcpdf/fonts/Calibri.ttf', 'TrueTypeUnicode', '', 32);
