Answer 1

respond_to do |format|
  format.html { render template: 'invoices/show' }
  format.pdf  do
    render pdf: 'invoices/show',
           template: 'invoices/show', 
           formats: :HTML, 
           encoding: 'utf8'
  end
end

Answer 2

Still i can see the special characters in the PDF. Below is my code

pdf = WickedPdf.new.pdf_from_string(page_html,:page_size => "A3") 

  send_data(pdf, 
    :filename => "my_pdf_name.pdf", 
    :formats => 'HTML', 
    :encoding => 'utf8',
    :disposition => 'attachment') 
  end
