Emphasis nodes not working with surrounded Chinese chars and Chinese punctuations

[weareoutman]

Initial checklist

• I read the support docs
• I read the contributing guide
• I agree to follow the code of conduct
• I searched issues and discussions and couldn’t find anything (or linked relevant results below)

Affected package

@mdx-js/[email protected]

Steps to reproduce

Go to the official playground and paste:

匹配*“abc”*字符

It generates:

{
  "type": "root",
  "children": [
    {
      "type": "paragraph",
      "children": [
        {
          "type": "text",
          "value": "匹配*“abc”*字符"
        }
      ]
    }
  ]
}

Actual behavior

With surrounded Chinese chars and Chinese punctuations, no emphasis nodes been generated.

Have to add spaces around the * to make it work.

Expected behavior

Expect to generate an emphasis node in the document.

Hi! This was closed. Team: If this was fixed, please add phase/solved. Otherwise, please add one of the no/* labels.

This is how markdown works in the CommonMark standard.
There is some discussion of changing the behavior if you'd like to add your voice to the standard discussion https://talk.commonmark.org/t/emphasis-and-east-asian-text/2491

I filed this issue because I have a gatsbyjs@v2 site that renders the above text as expected, as far as I know, it uses the @mdx-js/mdx too (but at v1.x). Now it can not work as expected with mdx v3, so I was thinking maybe it's a regression or something.

No it's an improvement; this is how commonmark works everywhere, in MDX since then now too

@weareoutman Could you try https://www.npmjs.com/package/remark-cjk-friendly plugin for the time being?

as far as I know, it uses the @mdx-js/mdx too (but at v1.x). Now it can not work as expected with mdx v3,

remark used in MDX v1 has not implemented this problematic feature yet.
