Notas de rodapé saindo da borda da página

Question

Ao usar títulos de seção longos e a paraopção de footmisc, as notas de rodapé são empurradas para fora da borda da página. Por exemplo

\documentclass{article}
\usepackage{lipsum}
\usepackage[para]{footmisc}
\begin{document}
    \section{This is a very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very long section title.}
        This is some text.\footnote{\lipsum[1-6]}
        \lipsum
\end{document}

Remova a paraopção para ver a diferença. Como posso evitar que a nota de rodapé ultrapasse os limites do texto?

Answer 1

A composição tipográfica (parágrafo) de notas de rodapé em (La)TeX é complicada. Uma introdução aos problemas enfrentados está na seção 9 dodocumentaçãodo manyfootpacote. No que diz respeito ao algoritmo de footmisc, sua paraopção precisa"mexer na rotina de saída"( footmiscdocumentação, p. 12). A página 13 do footmiscmanual afirma:

Fazemos uma caixa com o parágrafo de notas de rodapé e depois colocamos o conteúdo da caixa naquilo que vai sair \shipped.

Embora eu não esteja familiarizado o suficiente com a rotina de saída do LaTeX para ter certeza, suspeito que a "caixa" mencionada simplesmente não possa ser quebrada entre páginas.

Solução: Substitua footmiscpelobigfootpacote que apresenta o algoritmo mais avançado para notas de rodapé.

\documentclass{article}
\usepackage{lipsum}
\usepackage{bigfoot}
\DeclareNewFootnote[para]{default}
\begin{document}
    \section{This is a very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very long section title.}
