[REQUEST] detect fonts automatically

[xun-xh]

在提出功能请求之前,考虑在https://github.com/textualize/rich/discussions中发布反馈。

I have browsed all the relevant issues about "font". so many developers got an unexpected output, caused by it.

你如何提高富贵?

I think rich can add a feature that automatically detects terminal fonts. using ansi char when proportional font, otherwise not.

它能为你解决什么问题?

in that case, rich can work better in Asia environment

I'm afraid there isn't a way to detect the font or any possible font fallbacks in the terminal.

Interesting, but this page even warns that "This API is not recommended and does not have a virtual terminal equivalent". Presumably this would only work in the classic conhost and not the new Windows Terminal?

We do not recommend using this content in new products, but we will continue to support existing usages for the indefinite future.

Let me clarify: even if your feature request could be implemented, it would only work on Windows and specifically in the old conhost, not in the new default Windows Terminal?

[xun-xh]

yes, it would only work on Windows. but it also be used in the new terminal.

using ansi char when proportional font, otherwise not.

I'm not clear on what output you would expect with a proportional font. Very little of Rich would work without a monospace font.

Does this related to using Chinese characters in the terminal? Is it common for Chinese users to use proportional fonts?
