ubuntu 12.04下gedit中文乱码解决办法

如果txt不是UTF-8编码使用gedit打开时可能会乱码，可以这样解决解：
开终端输入：
gsettings set org.gnome.gedit.preferences.encodings auto-detected "['GB18030', 'GB2312', 'GBK', 'UTF-8', 'BIG5', 'CURRENT', 'UTF-16']"
gsettings set org.gnome.gedit.preferences.encodings shown-in-menu "['GB18030', 'GB2312', 'GBK', 'UTF-8', 'BIG5', 'CURRENT', 'UTF-16']"
