It loads the \pkgref{luainputenc} package for UTF-8 decoding
and sets \texttt{\textbackslash greekfontencoding} to LGR.

Hyphenation in Greek text parts fails (would require the
8-bit hyphenation patterns, i.a., a loader fix for LuaTeX).

% ¹TODO: Currently, defining \greekfontencoding must be done with
% 	 \def or \newcommand* and fails with \newcommand because
%    	 of the fragile string comparison using \ifx in greek.ldf!
