[akashsagar8]

Describe the Bug

I m using xhtml2pdf Version: 0.2.5 with django version 3.2 , I m trying to convert my hindi text into pdf but after converting pdf hindi text is not encoded with a right way , it gives black boxes or unreadable characters ------ I already used in html file meta encoding ="utf-8" line and also attached another libarary for hindi language like devnagriRegular.ttf file but not working

##this is my view function in django

def show_products(request):
products = crudajax.objects.filter(delete_flag=False).all()
template_path = 'pdf_report.html'
context = {'products': products}

response = HttpResponse(content_type='application/pdf')
response['Content-Disposition'] = 'attachment; filename="report.pdf"'

template = get_template(template_path)
html = template.render(context)

result = BytesIO()
# pisa.CreatePDF(
#  template, dest=response,  encoding='UTF-8')
pdf = pisa.pisaDocument(BytesIO(html.encode("UTF-8")), result, encoding='UTF-8')


if not pdf.err:
  return HttpResponse(result.getvalue(), content_type='application/pdf')
if pdf.err:
    return HttpResponse('We had some errors <pre>' + html + '</pre>')

Could you please provide some standalone code without relying on custom Django models and views, ideally without even using Django as this should be irrelevant in this case?
