Subject: русские буквы в EPS из Gnuplot
AVT>Когда Gnuplot графики на экране рисует, то русские буквы нормально выводится.
AVT>Перерисовываю график в EPS-формат, открываю его при помощи gv, русские буквы
AVT>"шифруются", то есть, в EPS одна кодировка, gv предполагает какую-то другую.
AVT>Вопрос: как правильно в гнуплоте использовать кириллические шрифты?
Патчить гнуплот.
Примерно так
