How to close *italics* this situation

[FreedomClannad]

I want to turn off italics in react-markdown in this case

There’s also a format for code, GitHub reads markdown, so you have to use code to explain your code.

react-markdown is for markdown too. You should use it for markdown. Not for other things.

Because I am going to show the smiles in chemistry, the molecular structure of * cccc2c( * )cccc2c1. Since there are two close * in it, the middle c1ccc2c( becomes italicized, so I just want to close the situation where there is only * xxx * .Because the data passed cannot be transferred in *.

@FreedomClannad as noted below https://github.com/orgs/remarkjs/discussions/1283#discussioncomment-8306297 creating a new markdown flavor is often problematic.
Instead considering leveraging markdown escapes

\*c1ccc2c(\*)cccc2c1

Or for more in-depth chemistry formatting consider using MathJax with MChem https://mhchem.github.io/MathJax-mhchem/ and https://github.com/remarkjs/remark-math

Welcome @FreedomClannad! 👋
react-markdown and remark build off micromark which can be customized https://github.com/micromark/micromark?tab=readme-ov-file#extending-markdown

That said, both human authors and most AI chatbots know how to write markdown (CommonMark).
Italics are part of CommonMark, changing the language will cause confusion with no benefits.
Just because it is possible to turn off italics and other constructs does not make it a good idea.
