Estou tendo um problema perturbador com \caption quando há caracteres diacríticos na legenda da imagem. Os diacríticos são exibidos perfeitamente, mas a legenda em si fica justificada à esquerda, não centralizada nesses casos. Alguma ideia de por que meu ambiente está causando tal comportamento na legenda?
Aqui está a classe de documento relevante que estou usando.

Normalmente as legendas multilinhas são justificadas. Se você quiser centralizar, você precisa usar \captionsetup{justification=centering}.
