gedit.preferences.encodings

問：如何解決「gedit」開啟檔案，產生中文亂碼的情形？

答：解決方法如下

python 範例

Xubuntu 16.04

執行

$ gsettings list-recursively | grep gedit | grep encodings

顯示

org.gnome.gedit.preferences.encodings candidate-encodings ['']
org.gnome.gedit.preferences.encodings candidate-encodings ['']
org.gnome.gedit.preferences.encodings candidate-encodings ['']

設定認得其他中文相關編碼

$ gsettings set org.gnome.gedit.preferences.encodings candidate-encodings "['UTF-8', 'BIG5', 'BIG5-HKSCS', 'EUC-TW', 'GB18030', 'GB2312', 'GBK', 'CURRENT', 'ISO-8859-15', 'UTF-16']"

觀看設定後的值

$ gsettings get org.gnome.gedit.preferences.encodings candidate-encodings

顯示

['UTF-8', 'BIG5', 'BIG5-HKSCS', 'EUC-TW', 'GB18030', 'GB2312', 'GBK', 'CURRENT', 'ISO-8859-15', 'UTF-16']

恢復預設值

$ gsettings reset org.gnome.gedit.preferences.encodings candidate-encodings
