I am writting a document in Spanish in LaTeX and the overfull box warning pops up. It is because LaTeX is trying to break the line with a word that has an accent. Because of this, that part of the document looks kind of bad because it goes over the margin. Is there a way to solve this?
Try the sloppypar enviroment in latex, it tells LaTeX to adjust word spacing less strictly.
\begin{sloppypar}
%your word / paragraph
\end{sloppypar}
