Devextreme datagrid pdf export font support

Hello!

I'm trying datagrid's pdf export feature in 20.2.3, but having issues with our specific fonts (Croatian).
I went on jspdf documentation to check for font support, and was trying to add font as suggested in documentation, it seems to work with custom text like headers, but does not work for datagrid table like column headers and columns itself…

Can you please share an example how to modify fonts inside exported datagrid's table to have our specific language letters?

I have attached pdf file with current progress and image of datagrid which I want to export… I have downloaded .ttf Roboto Normal with support for Croatian and I was using method described in jspdf documentation As you can see in attached pdf - header is giving our specific letters but table layout does not…

Code I'm using for exporting is:

JavaScript
//pdf test
function exportToPDF(e, fileName, owner, fontSize) {
    //instanca za pdf
    var doc = new jsPDF();

    // add the font to jsPDF
    //pdfFont variable is base64 string declared outside of this function!!
    doc.addFileToVFS('Roboto-Regular-normal.ttf', pdfFont); 
    doc.addFont('Roboto-Regular-normal.ttf', 'Roboto-Regular', 'normal');
    doc.setFont('Roboto-Regular');

    //font
    let fs = 10;
    if (fontSize) fs = fontSize;
    doc.setFontSize(fs);
    //stranica
    let pageHeight = doc.internal.pageSize.height;
    let pageWidth = doc.internal.pageSize.width;
    //headeri
    if (owner) doc.text(owner, 15, 10, { align: 'left' });
    //header and font size
    let ht = "ŠĐŽĆČPžđščć"; // fileName === undefined ? e.element[0].id.replace('Grid', '') : fileName;
    doc.setFontSize(fs + 2);
    doc.text(ht, pageWidth / 2, 10, { align: 'center' });
    //regular font size
    doc.setFontSize(fs);

    //devextreme example
    var dataGrid = e.component; //$("#gridContainer").dxDataGrid("instance");
    DevExpress.pdfExporter.exportDataGrid({
        jsPDFDocument: doc,
        component: dataGrid
    }).then(function () {
        //test page numbers
        let pages = doc.internal.getNumberOfPages();
        for (let j = 1; j < pages + 1; j++) {
            doc.setPage(j);
            doc.text('Stranica ' + j + ' od ' + pages, pageWidth - 15, 10, { align: 'right' });
        }

        //saving
        doc.save((fileName === undefined ? e.element[0].id : fileName) + '.pdf');
    });
}

Thank you!

Boris
