Escrevendo grego em XeLaTeX com a fonte padrão

Question

eu quero fazeressecom a fonte crm10. Como eu posso fazer isso? Eu tentei algumas fontes, mas não gosto delas.

\documentclass{scrreprt}

\usepackage{fontspec}
\setmainfont{Times New Roman}
\setsansfont{Arial}
\newfontfamily\greekfont[Script=Greek]{Linux Libertine O}
\newfontfamily\greekfontsf[Script=Greek]{Linux Libertine O}
\usepackage{polyglossia}
\setdefaultlanguage{greek}

\begin{document}
\tableofcontents{}

\section{Αυτό είναι ελληνικά.}
{\bfseries Welcome to Greek:} Αυτό είναι ελληνικά

Or Russian: Привет

Or Hebrew: מה הבעיה?
\end{document}

Answer 1

As fontes CMU são baseadas em Computer Modern (e as fontes CB para grego):

\documentclass{scrreprt}

\usepackage{fontspec}
\setmainfont{CMU Serif}
\setsansfont{CMU Sans Serif}
\newfontfamily{\greekfont}{CMU Serif}
\newfontfamily{\greekfontsf}{CMU Sans Serif}
\usepackage{polyglossia}
\setdefaultlanguage{greek}

\begin{document}
\tableofcontents{}

\section{Αυτό είναι ελληνικά.}
{\bfseries Welcome to Greek:} Αυτό είναι ελληνικά

Or Russian: Привет

%Or Hebrew: מה הבעיה?
\end{document}

No entanto, não há suporte para hebraico.

Você pode oferecer suporte ao hebraico com uma fonte diferente e usando ucharclasses:

\documentclass{scrreprt}

\usepackage{fontspec}
\setmainfont{CMU Serif}
\setsansfont{CMU Sans Serif}
\newfontfamily{\greekfont}{CMU Serif}
\newfontfamily{\greekfontsf}{CMU Sans Serif}
\newfontfamily{\hebrewfont}{Linux Libertine O}[Scale=MatchUppercase]

\usepackage{polyglossia}
\setdefaultlanguage{greek}

\usepackage[Latin,Greek,Hebrew,Cyrillic]{ucharclasses}

\setTransitionsFor{Hebrew}{\begingroup\hebrewfont}{\endgroup}

\begin{document}
\tableofcontents{}

\section{Αυτό είναι ελληνικά.}
{\bfseries Welcome to Greek:} Αυτό είναι ελληνικά

Or Russian: Привет

Or Hebrew: מה הבעיה?
\end{document}
