var containsTestText = (`На берегу пустынных волн
Стоял он, дум великих полн,
И вдаль глядел. Пред ним широко
Река неслася; бедный чёлн
По ней стремился одиноко.
По мшистым, топким берегам
Чернели избы здесь и там,
Приют убогого чухонца;
И лес, неведомый лучам
В тумане спрятанного солнца,
Кругом шумел.
Τη γλώσσα μου έδωσαν ελληνική
το σπίτι φτωχικό στις αμμουδιές του Ομήρου.
Μονάχη έγνοια η γλώσσα μου στις αμμουδιές του Ομήρου.
