我有一个运行烧瓶应用程序（python 3）的网站，当我尝试生成 pdf 时出现此错误：

Traceback (most recent call last):
  File "./web/frontend/printr.py", line 204, in generate_files
  File "/env/flask3/lib/python3.5/site-packages/pylatex/document.py", line 228, in generate_pdf
    stderr=subprocess.STDOUT)
  File "/usr/lib/python3.5/subprocess.py", line 626, in check_output
    **kwargs).stdout
  File "/usr/lib/python3.5/subprocess.py", line 708, in run
    output=stdout, stderr=stderr)

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "/env/flask3/lib/python3.5/site-packages/flask/app.py", line 1982, in wsgi_app
    response = self.full_dispatch_request()

编码：

try:
    doc.generate_pdf(file,clean_tex=True)
except Exception as e:
    doc.generate_pdf(file,clean=False,compiler='xetex')

选项 clean=False 转储了许多包含 *.tex 的文件，因此在服务器上使用命令行我再次尝试 (pdflatex file_name.text) e 得到特定错误：

! Package inputenc Error: Unicode char ‐ (U+2010)
(inputenc)                not set up for use with LaTeX.

在这里检查一种解决方案，我在文件中手动添加以下行：

\DeclareUnicodeCharacter{2010}{-}% support older LaTeX version

并且工作了！

但是我如何使用 PYLATEX 做到这一点？有其他方法来处理这种情况吗？因为在我看来，设置所有不能用乳胶处理的 UnicodeCharacter 太难了。

我修复了更改编译器。XeTeX 和 LuaTeX 将让您输入 unicode 而不会抱怨。

    if output == 'pdf':
        try:
            doc.generate_pdf(file,clean_tex=True)
        except Exception as e:
            doc.generate_pdf(file,clean=False,compiler='lualatex')
    else:
        doc.generate_tex(file)
