After the questions:

  1. How to set the english option to abntex2cite bibliography package?
  2. What is the difference between bibtex and biblatex?

I am trying to migrate to biblatex as it seems more up-to-date state-of-the-art. But my unicode characters as é are not working anymore. If my bibliography contains a letter such as é, I get a very unpleasant error:

test3.tex:42: Undefined control sequence 
...
test3.tex:42:  ==> Fatal error occurred, no output PDF file produced!

On line 45 is the line right after \printbibliography which brought me to the questions:

  1. Biber/BibLaTeX \printbibliography causes "undefined control sequence" in the proceeding line
  2. Undefined control sequence in \printbibliography (biblatex)

Leading me to find out the é letter is causing this very strange error.

Running this minimal example you will get the error mentioned:

}

\end{filecontents*}

\begin{document}

    Citing \cite{assis08}

    \printbibliography

\end{document}

But if you edit the bibliography and remove the é letter, then it is successfully build, however with the letter é missing:

enter image description here

Though if I replace the é by {\'e} it is correctly displayed with no errors:

enter image description here

However it is not nice to do so with my text. They said on the question What is the difference between bibtex and biblatex? biblatex is compatible with UTF-8:

You should consider switching to biblatex when you often have style guides for which you do not have appropriate BibTeX styles, or when you need to use UTF-8 for some reason.

Then why my document is not accepting UTF-8?

Here is my compilation log of the minimal example, using the {\'e} character:

  • Weird. \'e would give me an error with Biber/Biblatex, so I'm forever switching entries to unicode to avoid the errors. (I have old entries which don't get updated until they cause a problem when they're next used, so if I haven't used them in a while ....). However, you do need \usepackage[utf8]{inputenc} for this to work. So if the class doesn't call it, you need to add it. – cfr Sep 8 '17 at 2:50
  • Also, don't surround the letter by curly brackets. You just endanger kerning. And make sure you're using appropriate fonts (T1, presumably). – cfr Sep 8 '17 at 2:52
  • Why have you given the .log for the case which works? Are you certain the .bib is actually UTF8 encoded? – cfr Sep 8 '17 at 2:56
  • @cfr Thanks! I added \usepackage[utf8]{inputenc} \usepackage[T1]{fontenc} to my preamble and it worked. I though the class abntex2 was already including it on the document. I gave the log which worked because I had it on hand while writing the question. I would have to generate the log which did not worked again, but I did not wanted to wait it build. – user Sep 8 '17 at 3:02
  • It is in your log file but I don't know what is pulling it in as the class doesn't mention it directly. And, of course, it doesn't work. But that could be ordering. – cfr Sep 8 '17 at 3:11

It works if you set the input encoding correctly by loading inputenc with the appropriate option.

\begin{filecontents*}{\jobname.bib}
@mvbook{assis08,
    author = {Machado de Assis},
    title = {Obra completa em quatro volumes},
    year = {2008},
    editor = {Aluizio Leite and Ana Lima Cecilio and Heloisa Jahn},
    editortype = {organizer},
    edition = {2},
    volumes = {4},
    publisher = {Nova Fronteira},
    location = {Rio de Janeiro},
    series = {Biblioteca luso-brasileira. Série brasileira}
}
\end{filecontents*}
