IntelliJ encoding cannot change problem __ encoding

About IntelliJ file garbled problem, online already have a lot of solutions, basically is the line of the pass.

Today made a mistake, cause IntelliJ open Java file garbled (previously shown normal), try to modify the compiler tool by changing file encoding, engineering, file encoding, no effect, file encoding display is an exclamation point (!), Is that your current file encoding is not modifiable. Restart IntelliJ, or the same, tangled for a long time, and finally to see the MyEclipse code (this and IntelliJ with the same project-the same file), found that the MyEclipse set the encoding caused the IntelliJ file encoding can not be changed. Turn off the MyEclipse, then reset the code, OK, everything works.

Toss for a long time, is a lesson, here to share to everyone, do not simultaneously with MyEclipse and IntelliJ to open a project, may lead to some unnecessary problems.
