\documentclass{article}

\usepackage[utf8]{inputenc}

\begin{document}

zzz èse zzz

\end{document}

If you take the above file and save it in latin-1 (iso-8859-1) encoding then it produces the error below matching your screenshot. If you save it in UTF-8 which is the encoding that has been declared to LaTeX then it runs without error.
