How to use mdast-util-from-markdown to support Chinese and emphasis when parsing

[rxliuli]

As in the title, the current standard markdown cannot parse content that contains Chinese and emphasis at the same time.

For example **真没想到我这么快就要死了，**她有些自暴自弃地想着。, will get <p>**真没想到我这么快就要死了，**她有些自暴自弃地想着。</p>, expect to get <p><strong>真没想到我这么快就要死了，</strong>她有些自暴自弃地想着。</p>

There is a PR about this issue open in cmark for 6 years and still not resolved, ref: commonmark/cmark#208.
I'd like to know how to solve this problem myself directly through the plugin. I read some readme and it seems the entry is mdastExtension or micromark extension, but I'm still not quite sure what to do. Asking GPT-4 did not yield meaningful examples.

Hi. Our projects follow CommonMark: standard markdown. Particularly around parsing.

So, a) if possible you should discuss on the issue you found.

b) can you use **真**，她。 instead of **真，**她。?:

**真，**她。

**真**，她。

**真，**她。

真，她。

and c) you can use ​ to force punctuation around the characters.
Showing all possible examples:

1. ​**真，**她。
2. **​真，**她。
3. **真，​**她。
4. **真，**​她。
5. ​**​真，**她。
6. ​**真，​**她。
7. ​**真，**​她。
8. **​真，​**她。
9. **​真，**​她。
10. **真，​**​她。
11. ​**​真，​**她。
12. ​**​真，**​她。
13. ​**​真，​**​她。
14. ​**真，​**​她。
15. **​真，​**​她。

1. ​**真，**她。
2. **​真，**她。
3. **真，​**她。
4. 真，​她。
5. ​**​真，**她。
6. ​**真，​**她。
7. ​真，​她。
8. **​真，​**她。
9. ​真，​她。
10. 真，​​她。
11. ​**​真，​**她。
12. ​​真，​她。
13. ​​真，​​她。
14. ​真，​​她。
15. ​真，​​她。

Looking at those, we see that 4, 7, 9, 10, 12, 13, 14, 15. All because of the asterisks you want to use as closing the emphasis, which used to have a punctuation before and not after them, and now has punctuation before and after them.

I'm currently using **真，** 她。, And remove extra whitespace via plugin when rendering to html, but this is not very friendly for other documentation maintainers, so I hope there is a way to directly support **真，**她。.
Also, I don't intend to discuss whether to modify the markdown specification, because its modification process is very slow. I'm just wondering if it's possible to render it properly with a plugin, and if so, how.

micromark is extendable. But a) you need to be a very good programmer, b) it’s going to get very complex, c) you shouldn’t do it because it isn’t markdown anymore.
Please read the entire “Extensions” chapter first: https://github.com/micromark/micromark#extensions.

I hope you can do so: if that issue can be solved, it helps many speakers of Chinese (and speakers of other East Asian languages)!
