    Hi there,

    Currently, Gravity PDF makes no guess work when registering custom fonts with Mpdf (the software used to generate PDFs). What that means is, since not all fonts support Open Type layout tables (what’s used to join the cursive Arabic font) we don’t enable this functionality at all.

    If you’d like to enable this yourself you can use the “mpdf_font_data” WordPress filter at priority 15 to modify the $fonts array and include the appropriate ‘useOTL’ and ‘useKashida’ options for your custom font. That might look like this:

    
add_filter( 'mpdf_font_data', function( $fonts ) {
    ?if ( isset( $fonts['notosans'] ) ) {
        $fonts['notosans']['useOTL']     = 0xFF;
        $fonts['notosans']['useKashida'] = 50;
    ?}
    return $fonts;
?}, 15 );

    You’ll need to adjust ‘notosans’ to the font key assigned to your font, and adjust ‘useOTL’ and ‘useKashida’ as appropriate to your font family.

    really thanks for your quick reply
    I have solved my problem with another way!!
    it is maybe useful for other person who look for solution..

    I used Iransan.ttf (regular-bold-italic-bold/italic) font and then upload it to font directory in PDF_EXTENDED_TEMPLATES and then rename them to XB Riyaz (regular – bold- italic-bold/italic).

    it solved my problem

    but thank you anyway

    Great to hear that, Mohammed! FYI, Gravity PDF 6.0 (currently in beta) has a full overhaul of our Custom Fonts system and any fonts that support it will automatically enable OTL mode.
