🐛 问题描述

当前的做法，默认开启markdown语法，其在显示和复制时的处理有非常大的bug 如果用户在输入框键入3*4（任何基本的数学式），那么聊天气泡中就会变成3 4。用户从聊天气泡中复制后的文字就会变成34

在对AI返回的文字的显示上也有bug，见https://github.com/lobehub/lobe-chat/issues/2819#issuecomment-2156223674

另外 默认对用户输入开启markdown语法并非最佳做法 对于广大群众，markdown闻所未闻。应默认多数用户不知道markdown语法（这是合理的假设，也是openai chatgpt网页端的默认行为） 不过鉴于修改的难度。可以先默认开启markdown语法，但是要把我上面说的显示和复制bug改掉。

🚦 期望结果

在这件事情上，作者可参考openai chatgpt网页端的默认行为。openai在这方面行为细节的处理是极为优秀的。照抄即可。 两个例子 https://github.com/lobehub/lobe-chat/issues/2819#issuecomment-2156222993 https://github.com/lobehub/lobe-chat/issues/2819#issuecomment-2156223674

🐛 Problem description

The current approach is to enable markdown syntax by default, which has very big bugs in its display and copy processing. If the user types 3*4 (any basic mathematical formula) in the input box, the chat bubble will become 3 4. The text copied by the user from the chat bubble will become 34

in addition Turning on markdown syntax by default is not a best practice For the masses, markdown is unheard of. It should be assumed that most users do not know markdown syntax (this is a reasonable assumption and is also the default behavior of the openai chatgpt web page) However, given the difficulty of modification. You can first enable markdown syntax by default, but you need to correct the two bugs I mentioned above.

📷 Steps to reproduce

🚦 Expected results

Then when they type , \, etc. symbols, it should not be represented as markdown syntax in the dialogue bubble. At the same time, when copying the text in the speech bubble, symbols such as \ should also be restored

In this matter, the author can refer to the default behavior of the openai chatgpt web page. OpenAI's handling of behavioral details in this area is extremely excellent. Just copy it.

我的建议是，响应还是按markdown显示，提示可以给一个选项是否启用markdown渲染

不知道好不好做？

My suggestion is that the response should still be displayed in markdown, and the prompt can give an option whether to enable markdown rendering.

Don't know if it's easy to do?

你图片里的显示应该是模型输出的问题，而不是渲染问题，你可以点击消息旁边的编辑看一下，他写的是 *3*4*5* 还是 *3\*4\*5*，前者说明是模型输出错误

The display in your picture should be a problem with the model output, not a rendering problem. You can click the edit next to the message to see if it says *3*4*5* or *3\*4\*5 *, the former indicates that the model output is wrong

确实是模型输出错误。

这个建议我感觉很好

It is indeed a model output error.

I feel good about this suggestion
