问题描述

我正在Django网站上开发发票PDF生成器。我使用 xhtml2pdf 。似乎可行,但编码不正确。使用变音符号时出现错误的符号/字符。

I'm working on an invoice PDF generator on my Django website. I use xhtml2pdf. It seems to be working but encodings is not correct. There are wrong signs/characters when I use diacritics.

这是一个视图:

def render_to_pdf(template_src, context_dict):
    template = get_template("pdf/pdf.html")
    context = context_dict
    html  = template.render(context)
    result = StringIO.StringIO()

    pdf = pisa.pisaDocument(StringIO.StringIO(html.encode('utf-8'), result)
    if not pdf.err:
        return HttpResponse(result.getvalue(), content_type='application/pdf; encoding="utf-8"')
    return HttpResponse('We had some errors<pre>%s</pre>' % escape(html))

这是html:

<!DOCTYPE html>
<html>
  <head>
    <meta charset="UTF-8">
    <title>title</title>
  </head>
  <body>
    <p>Č š ž Ž x y ľ ĺ ó</p>
  </body>
</html>

这是生成的pdf:

This is the generated pdf:

推荐答案

尝试将字体网址添加到您的html中,不要忘记替换路径和名称

Try add font urls to your html, don't forget to replace path and name

<!DOCTYPE html>
<html>
  <head>
      <style>
        @font-face {
        font-family: FreeSans;
        src: url("/usr/share/fonts/truetype/freefont/FreeSans.ttf");
        }

        body {
        font-family: FreeSans;
        }
    </style>  
    <meta charset="UTF-8">
    <title>title</title>
  </head>
  <body>
    <p>Č š ž Ž x y ľ ĺ ó</p>
  </body>
</html>
