There are two modes of dealing with file encoding:
- Converting: the contents of the editor are stored in a different encoding. So doing, the contents of the underlying file change, but the contents of the editor stay unchanged.
- Reloading: the underlying file, opened in the editor, is shown in an encoding that differs from its original one. So doing, the contents of the editor can change, but the underlying files does not.
IntelliJ IDEA suggests the following major ways to change encoding:
- Using the File Encodings page of the Settings dialog, for directories and for the files that do not contain encoding information.
- Using the Status bar or menu command, for individual files that do not contain encoding information.
- Using the editor, for individual files that contain encoding information.
IntelliJ IDEA also supports configuring encoding for properties files.
- Open Project Settings dialog and select File Encodings.
- The File/Directory column shows the tree view of your project.
The Default Encoding column shows encoding for directories or files.
Click the Default encoding column for a directory or file you want to define
encoding for, and then choose the desired encoding from the drop-down list:
- Open the desired file in the editor.
- Change explicit encoding information. Use error highlighting to recognize wrong encoding
and press Ctrl+SpaceCtrl+SpaceCtrl+SpaceCtrl+SpaceAlt+SlashCtrl+SpaceCtrl+SpaceCtrl+Space or Ctrl+Back SlashCtrl+SpaceControl SpaceControl SpaceControl Space to have a list of available encodings displayed:
- Open the desired file for editing.
- Do one of the following:
- On the main menu, point to .
- Click file encoding on the Status bar.
- Select the desired encoding from the pop-up window.
- If the selected encoding will change the file contents, IntelliJ IDEA shows a dialog box, where you can choose to file from disk, or it to a different encoding.
