seems the problem is () in url which is a valid character, based on https://www.w3schools.com/tags/ref_urlencode.ASP but also could be replaced with %28 and %29 and properly recognised for rendering

Thanks for the issue!

This seems to me like a renderer issue. Which renderer do you use? If I copy the link (with angle brackets) to e.g. GitHub's or Gitlab's comment field and press the "Preview" button, both correctly render the image.

The angle brackets should be allowed here.

GitHub preview I guess and maybe PyPI...

Works fine on GitHub. If not on PyPI, then that should be a PyPI bug I think.

I can confirm the issue with the latest version:

$ mdformat --version
mdformat 0.7.17 (mdformat_web: 0.1.0)

$ cat ./edge-case.md

# Edge case

[Split screen](https://en.wikipedia.org/wiki/Split_screen_(video_production))

$ mdformat ./edge-case.md
$ cat ./edge-case.md

# Edge case

[Split screen](<https://en.wikipedia.org/wiki/Split_screen_(video_production)>)

Instead, I would expect mdformat to let the link as-is, or URL-encode the parenthesis as @Borda suggested:

# Edge case

[Split screen](https://en.wikipedia.org/wiki/Split_screen_%28video_production%29)

This isn't really a bug though, except in @Borda's CommonMark renderer. According to spec the link should render the same with the angle brackets. @kdeldycke what do you use to render? As I showed in #416 (comment), GitHub renders this just fine.

Here's the spec: https://spec.commonmark.org/0.31.2/#link-destination
The original link only renders correctly because there is a "balanced pair of unescaped parentheses". I can accept a PR that changes the style to not add the angle brackets.
