When switching from Eclipse to IntelliJ IDEA When I edited the properties file, I got a lot of differences.
When the property file is encoded, it causes a lot of differences depending on whether the alphanumeric characters are uppercase or lowercase, which is a problem.
Unfortunately, it didn't seem to be possible to set it from the menu, It seems that it can be avoided by editing the property file
Add the following line to your idea.properties file. It seems that you can edit it by selecting Help → Edit Custom Properties.
