How to make xunit reporter avoid encode test messages.

[ybbpgfjtey]

Prerequisites

• Checked that your issue hasn't already been filed by cross-referencing issues with the faq label
• Checked next-gen ES issues and syntax problems by using the same environment and/or transpiler configuration without Mocha to ensure it isn't just a feature that actually isn't supported in the environment in question or a bug in your code.
• 'Smoke tested' the code to be tested by running it outside the real test suite to get a better sense of whether the problem is in the code under test, your usage of Mocha, or Mocha itself
• Ensured that there is no discrepancy between the locally and globally installed versions of Mocha. You can find them with: node node_modules/.bin/mocha --version(Local) and mocha --version(Global). We recommend avoiding the use of globally installed Mocha.

Description

The xunit reporter always encodes everything, but if there's some Chinese characters, the report file will
generate something like this:

<testsuite name="Mocha Tests" tests="1" failures="1" errors="1" skipped="0" timestamp="Thu, 29 Nov 2018 03:23:34 GMT" time="0.035">
<testcase classname="&#x767E;&#x5EA6;" name="&#x9996;&#x9875;" time="0.003"><failure>expected &#x27;&#x6D4B;&#x8BD5;&#x27; to equal &#x27;&#x9519;&#x8BEF;&#x27;
AssertionError: expected &#x27;&#x6D4B;&#x8BD5;&#x27; to equal &#x27;&#x9519;&#x8BEF;&#x27;
    at Context.&#x3C;anonymous&#x3E; (C:/Users/ybbpg/Desktop/node-test/test/test.js:10:17)</failure></testcase>
</testsuite>

Totally unreadable, is there any way to avoid this?

Steps to Reproduce

1. Make test.js file:

import "chai/register-should";

describe("中文测试", function () {
  it("测试", () => {
    "测试".should.equal("测试 Not Equal"); // Will get error
  });
});

2. run mocha using.

mocha --require babel-core/register --reporter=xunit --reporter-options output=report/jUnit.xml test.js

3. check report/jUnit.xml.

Expected behavior: [What you expect to happen]
Don't encode classname, name, and body of testcase.

<testsuite name="Mocha Tests" tests="1" failures="1" errors="1" skipped="0" timestamp="Thu, 29 Nov 2018 03:25:19 GMT" time="0.039">
<testcase classname="中文测试" name="测试" time="0.004"><failure>expected 测试  to equal 测试 Not Equal
AssertionError: expected 测试 to equal 测试 Not Equal 
    at Context.&#x3C;anonymous&#x3E; (C:/Users/ybbpg/Desktop/node-test/test/test.js:10:17)</failure></testcase>
</testsuite>

Actual behavior: [What actually happens]
Encode everything.

<testsuite name="Mocha Tests" tests="1" failures="1" errors="1" skipped="0" timestamp="Thu, 29 Nov 2018 03:25:19 GMT" time="0.039">
<testcase classname="&#x4E2D;&#x6587;&#x6D4B;&#x8BD5;" name="&#x6D4B;&#x8BD5;" time="0.004"><failure>expected &#x27;&#x6D4B;&#x8BD5;&#x27; to equal &#x27;&#x6D4B;&#x8BD5; Not Equal&#x27;
AssertionError: expected &#x27;&#x6D4B;&#x8BD5;&#x27; to equal &#x27;&#x6D4B;&#x8BD5; Not Equal&#x27;
    at Context.&#x3C;anonymous&#x3E; (C:/Users/ybbpg/Desktop/node-test/test/test.js:10:17)</failure></testcase>
</testsuite>
