I'm trying to use the figcaps package in an article to keep all figures at the end of the document. When I compile the following TeX code using pdflatex I get the following error message:
! Package inputenc Error: Unicode char \u8:�oS not set up for use with LaTeX.
Although it says to an inputenc error, when I try without using the figcaps, everything works smoothly.
Below is an example to illustrate my issue. Please make sure you have an image file named image_file. I have tried this sample a couple of times, and the error does not always raise, but in the PDF the captions look awful.
\documentclass[11pt,a4paper]{article}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage[english]{babel}
\usepackage{graphicx}
\usepackage[printfigures]{figcaps}
\begin{document}
\begin{figure}
\includegraphics[width=1.\textwidth]{image_file}
\caption{Location of the Southeast Brazilian Bight~(SBB) and detail of the São Sebastião Channel.}
\label{fig:Map}
\end{figure}
\end{document}
The error raises because I use a special character in the figure caption, in this case ã and I suppose a similar error would rise using any of the following characters: ñ, â, Ü, ...
I am aware that a workaround would be to use escaped codes such as \~a, for example.
However, I usually find it annoying to use these escaped codes and try to avoid them. Is there any other option?

utf8x, but it should be avoided, according to egreg, or God, as I like to call him. – Runar Jun 23 '16 at 20:21utf8x. – regeirk Jun 23 '16 at 20:29utf8x. – Runar Jun 23 '16 at 20:30utf8xbut characters replaced with "[Pleaseinsertintopreamble]".
