The accented Portuguese characters work well when compiled with pdflatex but not with xelatex giving an inputenc error. Why?
\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage[portuguese]{babel}
\usepackage[T1]{fontenc}
\author{Sérgio}
\title{Há muito açafrão}
\begin{document}
\maketitle
Words/letters with accents: Sérgio áéíóúçãõ.
\end{document}
If you put an accent over a single character, TeX uses information in the font metrics to shift the accent to take some account of the slope of the italic letters. Which is why the first one shifts. If you put an accent over a more complicated math list then it's just centered over the list.
I can guarantee you that using a code like this:
\documentclass{article}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage[spanish]{babel}
\begin{document}
Sólo una pequeña demostración.
S\'{o}lo una peque\~{n}a demostraci\'{o}n
\end{document}
Will produce a correct output like this:
Please make sure non of your packages required by your template or any other setting in your editor conflicts with the specifications mentioned above.
As David Carlisle said in the comments:
... so I would guess that your editor is making new files in utf8 but that file is copied from some original template and it is keeping its encoding. I don't know the editor but you should be able to force save to utf-8 (or just start a new file in utf8 and then cut and paste the old text in.

You shouldn't use
inputencwith XeLaTeX : it supposes your document is in utf8 encoding. And you shouldn't usefontenceither, since it manages fonts directly. Also, it is recommended to usepolyglossiarather than babel: it is tailored for XeLaTeX.Here is a code that works:
