Title: encoding request_body to utf-8 for Chinese post params

When post params has Chinese, error `incompatible character encodings: ASCII-8BIT and UTF-8 (Encoding::CompatibilityError)` will be raised. Just a quick fix.
I think it's same as this issue https://github.com/zipmark/rspec_api_documentation/issues/151
