如何在 django 中使用 xhtml2pdf 生成的 PDF 中显示表情符号字符?
How to display emoji characters in PDF generated using xhtml2pdf in django?
我正在尝试使用 xhtml2pdf 将 HTML 转换为 PDF,但无法正确呈现 HTML 中的表情符号字符,它们显示为黑框。我尝试了不同的字体,但仍然是同样的问题。

pisaStatus = pisa.CreatePDF(BytesIO(source), pdf, encoding='utf-8')
return pdf
if __name__ == "__main__":
pdf = convertHtmlToPdf(source)
fd = open(os.path.join('/home/userX/', 'test-%s.pdf' % time.time()), "w+b")
fd.write(pdf.getvalue())
fd.close()
所以我能够使用 Symbola 字体在 PDF 上获取表情符号,如下所示:
