[Tex/LaTex] problem with Greek in beamer (windows)

Question

I am trying to write my thesis presentation in windows with Beamer but i have an issue with Greek language.

when i want to add a definition from drop down menu , the letters dont appear right in the compiled file.

for example if i add Definition , in the compiled pdf appear Δεφινιτιον instead of Ορισμος (Definition in Greek).

Answer 1

You have to pass the greek option to the class:

\documentclass[greek]{beamer}
\usepackage[utf8]{inputenc}
\usepackage{babel}
\usetheme{Warsaw}
\begin{document}
\begin{frame}
\begin{definition}
Η Αθήνα είναι η πρωτεύουσα της Ελλάδα
\end{definition}
\end{frame}
\end{document}
