Unicode Support for execute-request

[ystxn]

Bug Report

WDK's execute-request is not unicode compatible and transforms unicode characters to question marks in the outputs object returned.

Steps to Reproduce:

id: post
activities:
  - execute-request:
      id: init
      on:
        message-received:
          content: post
      method: POST
      url: https://httpbin.org/post
      headers:
        Content-Type: multipart/form-data
      body:
        text: Hello こんにちは世界

  - execute-script:
      id: debug
      script: println init.outputs

  - send-message:
      id: sendResponse
      content: ${init.outputs.body.form.text}

Expected Result:

1. Console will print the original text: Hello こんにちは世界
2. Bot will send original text: Hello こんにちは世界

Actual Result:

1. Console prints: Hello ???????
2. Bot sends: Hello ???????

Environment:

WDK 1.1.0
