A Faraday Middleware sets body encoding when specified by server.

Response body's encoding is set always ASCII-8BIT using with net/http adapter. Net::HTTP doesn't handle encoding when server specifies encoding in content-type header. Sometimes we caught an Error such as the following:

body = Faraday.new(url: 'https://example.com').get('/').body
# body contains utf-8 string. ex: "赤坂"
body.to_json
# => raise Encoding::UndefinedConversionError: "\xE8" from ASCII-8BIT to UTF-8

That's why I wrote Farday::Encoding gem.

SEE ALSO: response.body is ASCII-8BIT when Content-Type is text/xml; charset=utf-8

Add this line to your application's Gemfile:

gem 'faraday-encoding'

And then execute:

$ bundle

Or install it yourself as:

$ gem install faraday-encoding

require 'faraday/encoding'

conn = Faraday.new do |connection|
  connection.response :encoding  # use Faraday::Encoding middleware
  connection.adapter Faraday.default_adapter # net/http
end

response = conn.get '/nya.html'  # content-type is specified as 'text/plain; charset=utf-8'
response.body.encoding
# => #<Encoding:UTF-8>
