Huh, so if I'm reading this right - the font is changing weight ever so slightly when there's a run of Chinese characters present in the row. That's super weird - @skyline75489 any ideas why this might be happening? Would your work on the FontInfo, text complexity, perhaps help here?

[DHowett]

It looks like it's causing a font fallback for the entire run (??????) which should not be possible.

@notes365 can you provide your Terminal configuration here? I wonder if there’s something special about font in your settings.

i reinstalled version1.6.10571.0, reported the following error

but everything is ok, may be the reason for the font Cascadia Mono

i reinstalled version 1.7.1091.0 then change the font to Consolas, still rendering abnormal

I'm unable to reproduce this bug...
I've tried to enter some western/latin characters, followed by Chinese, the same way the issue was reported and I couldn't notice any shifts in font appearance.

Maybe this is some ClearType issue? Or some packages are missing on Windows?
It would be interesting whether this issue reproduces on a different machine.
