I have a project in which a non UTF8 encoding is required. If I change a symbol (Ctrl+Shift+R by default) and if that symbol exists in many files (some already open, some not), the files in questions will be modified according to my symbol change request but it seems that the ones that are not open at the moment when the change is applied will be corrupted by being saved in some encoding other that the one configured for the project (or at least other than the one the file is currently saved with). Typically, I see all accented letters of my ISO-8859-1 encoding disappear.
