MWS get_report encoding issues not UTF-8 but UTF8

[NaitoYuki]

Hi,
Thanks for the this library. We are using MWS::Reports::Client.

We are using get_report(request_id) method for _GET_MERCHANT_LISTINGS_ALL_DATA_ report.

some response is the below error. unknown encoding name - UTF8

28640:E, [2020-03-25T19:50:14.690306 #5105] ERROR -- : unknown encoding name - UTF8

I found the error is the below. match_data is UTF8.

Seems to me something is the wrong encoding pattern.

So, We are avoiding this error for this patch code.

config/initializers/monkey_patches/flat_file_parser.rb

module Peddler
  class FlatFileParser < SimpleDelegator
    def scrub_body!(encoding)
      return if body.encoding == Encoding::UTF_8

      set_charset = content_charset rescue Encoding::UTF_8.to_s
      self.body = body.dup.force_encoding(set_charset || encoding)
    end
  end
end

We hope this error will be resolved.
