I want to use pdftron and all things work perfect but when i copy text from pdf some characters convert to blank square and question mark, any idea?
here is my pdf.
I wrote this code:
WebViewer({
path: '/assets/plugins/pdftron',
initialDoc: '/practical.pdf',
fullAPI: true,
disableLogs: true
}, document.getElementById('pdf')).then((instance) => {
// PDFNet is only available with full API enabled
const { PDFNet, docViewer } = instance;
let Feature = instance.Feature;
instance.disableFeatures([Feature.NotesPanel]);
docViewer.on('documentLoaded', () => {
// call methods relating to the loaded document
});
instance.textPopup.add({
type: 'actionButton',
img: '/language.svg',
onClick: () => {
const quads = docViewer.getSelectedTextQuads(docViewer.getCurrentPage());
const text = docViewer.getSelectedText();
$("#out-pdf").html(text);
console.log(quads);
},
});
});
