It's an Atom package for automatically adding
# encoding: utf-8 at beginning on every Ruby file with non-ASCII characters. It saves the time from doing a boring task for adding the encoding declaration manually. There are many options to implement this tool either on current opened editor (right click on wherever in the code then
Add #encoding utf-8 or go to packages then Auto Encoding for Ruby), on selected file (inside tree view, right click on the file then
Add #encoding utf-8 ) or on selected directory (in tree view and right click too). When choosing a selected directory, the package adds the encoding declaration in all Ruby files inside the selected directory.
Good catch. Let us know what about this package looks wrong to you, and we'll investigate right away.
