нашёл в интернете такое решение проблемы:
"Выполните в терминале команду:
gconf-editor /apps/gedit-2/preferences/encodings
Откроется Редактор Конфигурации GNOME. В нем откройте для редактирования ключ auto_detected.
В появившемся окне редактирования переместите нужную вам кодировку вверх, так, чтобы она находилась сразу после UTF-8.
Нажмите OK и закройте редактор."
но у меня не отображается encodings
