Closes #890

Thanks, I'll try to take a closer look in a few days.

Do you have any feeling about whether the spec has willingness to adopt something like this out of the box?
Ideally something like this wouldn't even be an option, just the default behavior from the spec.

I think that "Out of the box" is a little bit too early for a while. It is not strictly compatible with CommonMark. It is a provisional spec and probably going to be revised once more (to peek the character two ahead to deal with some following variation sequences)
It is fine to strongly recommend this.

Please add a link to where these constants are coming from

Do you mean:

How can we refer to the polyfilled Rune easily?

    <ProjectReference Include="..\Markdig\Markdig.csproj">
      <Aliases>global</Aliases>
    </ProjectReference>

forces us to add extra Markdig:: everywhere.

I'd ifdef the test to just NET

[tats-u]

I have no where should be #ifdef NET'ed.

[MihaZupan]

Does something like this not work?

#if NET
[Test]
[TestCase(...)]
public void TestCheckOpenCloseDelimiterCjkFriendly(...)
{
    // ...
}
#endif

As I suspected, it is not concerned with the target framework of the main project. It only refers to the target of the testing project.
