The Greek letters in my document are appearing as semicolons. Why?

Question

Using a solution provided by @egreg, I am experiencing some strange output when using the code:

\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage[greek,english]{babel}
\usepackage{lmodern}

\begin{document}

This is in English, but we also have
\textgreek{μια φράση στα ελληνικά}

\end{document}

When I compile, the output I get has semicolons in the place of the Greek letters:

My log file:

Any thoughts?

Answer 1

For strange reasons, TeXShop by default saves files in ISO-Latin-9 encoding. Indeed, if I run the following file

% !TEX encoding = IsoLatin9

\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage[greek,english]{babel}
\usepackage{lmodern}

\begin{document}

This is in English, but we also have
\textgreek{μια φράση στα ελληνικά}

\end{document}

I get the semicolons.

Change the first line to

% !TEX encoding = UTF-8 Unicode

and the problem will disappear.

Also go to the preferences and change the default encoding:

The relevant drop-down menu is under “Encoding”. This will save all files in UTF-8.
