"\x89" from ASCII-8BIT to UTF-8 (Encoding::UndefinedConversionError)

[tdegrunt]

Hi,

I've checked out this repository and wrote the below simple test.rb, while using the below image:

require 'mongoid-grid_fs'

Mongoid.configure do |config|
  config.connect_to('mongoid-grid_fs_test')
end

file = File.open('./signature.png')
grid_file = Mongoid::GridFs.put(file.path)

If I execute this with bundle exec ruby test.rb, I'm getting the following exception.
Am I doing something wrong or overlooking something?

Same problem here but if I downgrade bson to 3.1.1 no problem.

[pezholio]

Yup, same here. Pinning to 3.1.1 fixes this, because 3.1.2 encodes to UTF-8 and then switches to binary.
