chat message can not show special characters

[ZhaoVitapublic]

We have a problem by sending chat message with special characters like _, * etc.
By sending messages, the markdown parser doesn't offer the escape opportunity to present some special character like _, etc..

For example , we want send a normal message with a word like "Bla_bla_123" in italic:

We expect to show as
Bla_bla_123,
but rocket chat shows the message like
Bla_bla_123_ .

Reference see following code on https://github.com/RocketChat/Rocket.Chat/blob/develop/packages/rocketchat-markdown/markdown.js line 31:

// Support _text_ to make italics
msg = msg.replace(/(^|&gt;|[ >*~`])\_([^\_\r\n]+)\_([<*~`]|\B|\b|$)/gm, '$1<span class="copyonly">_</span><em>$2</em><span class="copyonly">_</span>$3');

Is there any possibility to handle this problem?

Can confirm, tested on demo.rocket.chat

_Bla_bla_123,_ becomes to Bla_bla_123,_

Yes, I'm also missing a general way to escape all Markdown special characters. GitHub allows this by prefixing any special characters with a backslash. For example:

_test_ becomes test
\_test\_ becomes _test_
\`\`\` becomes ```

@rocket-cat close

Closing this in favour of #8989.
