Support setting a fallback font

Describe the solution you'd like?

Sometimes some fonts do not support some special characters, which will cause display errors. We hope that fallback fonts can be supported.

Is this feature working in progress?
It is opened for about two years.

I second this, it would remove the need for patched fonts, and it's a very common feature supported by all modern terminals.

It's a shame this is not something being worked on. It's already present in other terminals and I find it quite crucial as it allows the use of non-patched fonts with a specialised nerd font that includes glyphs and icons.

+1 - every modern terminal/editor supports fallbacks, it seems like an odd feature to be missing with how icon-heavy new tooling seems to be

[calops]

I'll go beyond that: the state of the art these days is for the terminal emulator to not only bundle a patched font as a default fallback out of the box, but also handle all box-drawing and powerline symbols natively.

This means actually drawing these symbols perfectly rather than rendering them as font glyphs. This is particularly useful as patched fonts are kind of a hack that isn't working well in plenty of non-default cases (for example, when you change the line spacing), as well as many default ones (the spacing for the fallback font may not be the same as the spacing for the primary font).

Would definitely like fallback fonts; much better solution than patching fonts to get NerdFont support.

[AurevoirXavier]

Please place greater emphasis on this and elevate its priority, particularly for a contemporary terminal. For instance, there are numerous symbols in the current Git workflow.

I just made an icon font set for brand icons. I'm looking forward to the fallback font so that users can have a chance to test it:

• Use a viewbox with the same aspect ratio as the icon entity simple-icons/simple-icons-font#211

Definitely more flexible than embedding NerdFont or whatever. I'm personally using MacOS SF Symbols in my prompt so the fallback font would be the only solution.
