Invoice error caracter Asian Font

Somebody can help me?

I follow a previous support task.

I add in function.php

add_filter( ‘wpo_wcpdf_mpdf_options’, function( $options ){
// get defaults
$defaultConfig = (new Mpdf\Config\ConfigVariables())->getDefaults();
$fontDir = $defaultConfig[‘fontDir’];
$defaultFontConfig = (new Mpdf\Config\FontVariables())->getDefaults();
$fontData = $defaultFontConfig[‘fontdata’];

// setup custom font dir & font data
$customFontDir = WPO_WCPDF()->settings->get_template_path() . ‘/fonts’;
$customFontData = [
‘Kanit’ => [
‘R’ => ‘Kanit.ttf’, // use ‘B’,’I’,’BI’ keys for Bold, Italic & Bold Italic respectively
‘useOTL’ => 0xFF,
],
];

// merge in options
$options[‘fontDir’] = array_merge( $fontDir, [ $customFontDir ] );
$options[‘fontdata’] = $fontData + $customFontData;

return $options;
} );

I am using a custom template and the font is declared on the css. I do not understand why its not working, i have ? instead of the THAI letters. I need help

Somebody can answer me?

Hi! The filter you are using here is for the mpdf extension, but if you are already using the mpdf extension, then a custom font should not be required for showing Thai characters. Are you sure you are using the mpdf extension and not the default/built-in engine (dompdf)?

if you are not using mpdf, you can just follow the instructions from the documentation: https://docs.wpovernight.com/woocommerce-pdf-invoices-packing-slips/using-custom-fonts/
