\section*{Cyrillic fonts to match Latin Modern}

Latin Modern does not work for the Cyrillic script. If the CM-Super package
is installed, it will be used instead. If not, bitmapped LM fonts are used
for cyrillic text. The \emph{cmlgc} package provides free Cyrillic
vector-fonts matching CM.

\section{Заголовок}

первый пример: \glqq{}Здравствуй, мир!\grqq{}

\texttt{"Здравствуй, мир!"}

\section{section title in latin script}

Babel does not switch the font encoding when changing between Russian and
English. As a standard font encoding, T2A provides basic Latin. However, 
the TeX Gyre fonts provide better support for accented Latin letters
(compare the result of drag-and-drop of the following lines from the PDF
rendering).

\selectlanguage{english}

T2A \glqq{}Viele Grüße!\grqq{} \texttt{"Hello world!"}

\fontencoding{T1}\selectfont
T1 \glqq{}Viele Grüße!\grqq{} \texttt{"Hello world!"}
