I have encoding set to UTF-8. Now Idea changes non-utf-8 files to utf-8. However there are some files that I want to keep in their original encoding. How do I do that? From Settings > Editor > File Encodings I can make exceptions to specific file but I would like to add specific encoding for entire directory instead because there are hundreds of .csv files that need exception and adding them all manually is pain but having to edit them in other ide is also annoying.
