| Item | Description |
|---|---|
| IDE Encoding | Select encoding to be used for IntelliJ IDEA. |
| File/Directory | This column displays the project tree view. |
| Default encoding | This column displays encoding for a file or directory, if applicable. If encoding is
defined within a file, it cannot be configured, and is shown in grey font. If encoding
is configurable, click the Default Encoding column for a selected file or
directory, and choose encoding from the drop-down list.
Encoding information embedded in a file overrides the selected one; encoding information for the nested files or directories overrides that for the outer directories or the whole project. |
| Autodetect UTF-encoded files | Check this option, if you want IntelliJ IDEA to change file encoding to UTF, if at least one character encoded in UTF-8 or UTF-16 is detected in a file. |
| Default encoding for properties files | Use this drop-down list to define encoding for the properties files in a project. According to the Java API, the load(InputStream) / store(OutputStream, String) methods of the java.util.Properties class, use ISO 8859-1 encoding for input/output stream. It is advisable to use this encoding unless you have special reasons to change it. In this case, you can select the desired encoding from the drop-down list; in particular, you can use encoding defined for the whole project. |
| Transparent native-to-ascii conversion | Select this option to show in properties files the national characters (non-ISO 8859-1), stored as escape sequences. For more details refer to Configuring Encoding for Properties Files. |
