This is an excerpt from a rails console session:
2.1.1 :011 > x=User.new({name: 'x', email: 'x...@example.org', password:
'xxxxxxxx', password_confirmation: 'xxxxxxxx'})
=> #<User id: nil, name: "x", email: "x...@example.org", created_at: nil,
updated_at: nil, password_digest:

nil, admin: false>
2.1.1 :012 > x.save

We can see that everything works, and indeed, x.errors shows an empty
message list. However, I wonder what the warnings (?) "Binary data
inserted...." mean.
When I google this subject, the usual explanation is an encoding issue.
In my case, the data contain just 8 bit ASCII, as we can see here:
2.1.1 :014 > x.name.encoding
=> #<Encoding:ASCII-8BIT>
I probably don't have to worry about these messages, as my user is
created, but I would like to know out of curiosity....
