# TeX complains about a “Package inputenc Error” [closed]

Compiling a simple document, I get the following error:

On the line 166, there is a \begin{itemize} environment. I tried commenting it out and the error goes away, but there doesn't seem to be anything wrong with that part of code. I'm posting it below (from line 164 to 169):

\documentclass[12pt]{article}
\usepackage[a4paper]{geometry}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage[shortlabels]{enumitem}
\usepackage{graphicx}
\usepackage{titlesec}

\begin{document}

\begin{itemize}

\item[Presuposiciones] Son aseveraciones no expresadas. Son supuestos que el hablante hace
sobre lo que probablemente aceptará al oyente sin ponerlo en duda.
Para que un texto sea coherente que el emisor haya acertado en sus presuposiciones.
\item[Implicaturas] Se relacionan estrechamente con los actos de habla indirectos.

\end{itemize}

\end{document


What's happening?

check your input encoding , it should be utf-8 as there are some utf characters in your latex file – texenthusiast Jun 27 '12 at 15:26
@texlearner But the rest of the document loads fine. That's why it's weird. I mean, I have characters with accents everywhere. – Alenanno Jun 27 '12 at 15:27
I have added a minimal working example (I suppose it should work). – Alenanno Jun 27 '12 at 15:28
@texlearner Use a good editor. The character might have been a "NO-BREAK SPACE" (U+00A0) and it may be difficult to spot. On Emacs it's shown by a thin underscore. – egreg Jun 27 '12 at 15:44
@texlearner: See Why the end-of-line % in macro definitions?. – Caramdir Jun 27 '12 at 15:59

You have a control character after the full stop after duda. If you delete that then it all seems to work.
