Failed to execute 'btoa' on 'Window': The string to be encoded contains characters outside of the Latin1 range.

[iamyoki]

Describe the bug
Here is my test:

it.only('test', () => {
    cy.matchImage();
  });

First run is okay, but not after then.
I think it's related to my chinese character filename.

Here is the error message:

Error:       InvalidCharacterError: Failed to execute 'btoa' on 'Window': The string to be encoded contains characters outside of the Latin1 range.

Hi @iamyoki!
Thank you for the issue and PR 🙇

It seems that you've noticed the issue correctly - seems like non-latin characters need to be escaped since the filename is serialized into on anchor link. Let's try to get this PR merged quickly! 💪
