File | Settings | File Encodings
Use this dialog to configure encoding options for a project and for the entire IDE.
|IDE Encoding||From this drop-down list, choose the encoding to be used when no project is currently opened. The encoding will be applied, for example, when you specify the settings of a default project or check out sources from a version control storage. Choose System Default to have the default encoding of your operating system used or choose a specific encoding.|
|Project Encoding||From this drop-down box, choose the default encoding to use in the folders for which no encoding is appointed in the Default encoding field below. Choose System Default to have the default encoding of your operating system used or choose a specific encoding.|
|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.
13.1+If this check box is not selected, the national characters will not be shown.
Compare two representations of the national characters:
