ruby-on-rails – Wicked_pdf和utf8符号

在我生成的pdf中,我得到了这个

0,00 €

代替

0,00 €

Application.html.erb

<meta charset="utf-8">
  <meta http-equiv="content-type" content="text/html; charset=utf-8" />

show.html.erb

<%=number_to_currency item.total%>

解决方法

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