如何在 pylatex 中添加重音符号？

Question

嗨，我开始使用 pylatex。我尝试使用下面的代码生成 pdf，但只有当我从单词中删除重音符号时才有效información，但如果我不删除，它会提示错误。

        geometry_options = {"tmargin": "1cm", "lmargin": "1cm"}
        doc = Document(geometry_options=geometry_options, )
        doc.packages.append(Package('booktabs'))
        package = Package('babel', options='spanish')
        doc.preamble.append(Package('babel', options='spanish'))
        doc.preamble.append(Command('title', 'Resultado'))
        doc.preamble.append(Command('selectlanguage', 'spanish'))
        doc.preamble.append(Command('author', 'N'))
        doc.preamble.append(Command('date', NoEscape(r'\today')))
        doc.append(NoEscape(r'\maketitle'))

        with doc.create(Section('Resultados')):
            with doc.create(Subsection('Validaciones')):
                doc.append('¿Por que no puedo agregar acentos?')

            with doc.create(Subsection('Validaciones de información')):
                doc.append('')
        doc.generate_pdf('Resultados', clean_tex=False, compiler='pdflatex')
        tex = doc.dumps()

错误：
