Looks like this causes a bunch of unit tests to fail. Can you look into that?

[dyoshikawa]

@jshemas Thank you for your comment. Sure, I'm looking into those.

@jshemas The result of npm run mocha:unit has now become successful.

Hello, can also look into why the integration tests are failing? npm run mocha:int (You can just focus on the failing tests in encoding.spec.ts )

Sorry, I worked on unit tests only. I'll also check on that.

I have confirmed that the following test execution command passes all tests:

npx ts-mocha --recursive \"./tests/integration/encoding.spec.ts\" --timeout 10000

The errors that were occurring were due to files intended to be in euc-jp or Shift_JIS being encoded in utf-8 on openGraphScraperPages.

I have converted these files to the expected character encoding and temporarily hosted them on my github.io for testing purposes, so please check it out.

I have created a separate Pull Request regarding this issue.

• Encode the files in the intended character encoding openGraphScraperPages#2

Once it is merged into openGraphScraperPages, I will make further adjustments to this test.

Using response.clone() seemed to cause this test to fail.

Therefore, I made changes to avoid using clone() without altering the behavior. This resolved the error.

@jshemas I would be happy if you could rerun the test. Sorry to bother you while you're busy.

[jshemas]

Thanks for fixing this issue! PR looks good to me.

Changes are live in open-graph-scraper@6.4.0
