rake tasks fail with invalid byte sequence in US-ASCII
Add
#encoding: utf-8 to the first line of your Rakefile (or whatever file has the strange characters in)
Track down the rake file(s) at fault by deleting one at a time.
ie the files under lib/tasks/delete_me.rake
Then re-rake or restart which ever was giving you the issue. Once the issue is gonedo a git diff to see which file was the culprit and with your favorite editor change the encoding of the file.
ie.,
vim lib/tasks/delete_me.rake:set fileencoding=utf-8:wq
Then re-rake and you should be back in service.
First run
$ sudo gem install magic_encodingThen go into the folder and run
$ magic_encodingReady!
