In my work, we programmed PHP mostly and all the code files were made in ASCII, I'm doing some page inclusions and I often need to open the existing files and add new things.
I do this through Notepad ++, because whenever I open one of the existing Sublime codes, it changes the whole charset and buga the whole page.
How do I change the charset of Sublime to always open the file charset? Or change the standard charset of the sublime forever to ASCII?
