Greek and Latin letters in verbatim
Set the font encoding to T1 inside verbatim
:
\documentclass{article}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage[greek]{babel}
\usepackage{alphabeta}
\makeatletter
\renewcommand\verbatim@font{\normalfont\fontencoding{T1}\ttfamily}
\makeatother
\begin{document}
\begin{verbatim}
για κάθε t:
x1 = x0 + u*Δt
\end{verbatim}
\end{document}
My problem was fixed after refactoring the \usepackage
command:
\usepackage[english, greek]{babel}
and inserting the command
\selectlanguage{english}
before the verbatim
