[BUG] Regression in 8.13.0 on Windows: `echo 5%` prints just `5` instead of `5%`

[lydell]

Is there an existing issue for this?

• I have searched the existing issues

This issue exists in the latest npm version

• I am using the latest npm

Current Behavior

$ npm test

> test
> echo 5%

5

This happens since 8.13.0.

Expected Behavior

$ npm test

> test
> echo 5%

5%

8.12.2 prints 5% as expected.

Steps To Reproduce

1. Use Windows

2. With this package.json:

   {
     "private": true,
     "scripts": {
       "test": "echo 5%"
     }
   }

3. Run npm test

4. Notice how the percentage sign is gone.

Environment

• npm: 8.16.0
• Node.js: 18.7.0
• OS Name: Windows 10
• System Model Name: PC

Can confirm, stumbled upon it with different scenario:

# npx echo-cli Привіт

OS: Windows 10 with English locale.

this should work correctly as of npm@8.17.0, but please do reopen the issue if you can still reproduce it

Amazing!

For the curious following along, this was the fix I think: npm/run-script#98
