For example this: 𝔱𝔢𝔰𝔱
Emacs displays it like this:
I have noticed this just after a Windows update this morning (now version is 1903). I remember it was working well a few days ago. I tried
emacs -Q to not load any of my init files and the problem is still there.
I have another PC which is runninig Windows 1809, and on that PC it works correctly even if I run
emacs -Q. And on that PC if I place cursor at the 1st char of my example and do
C-u C-x = I can see the font is
uniscribe:-outline-Cambria-normal-normal-normal-serif-13-*-*-*-p-*-iso10646-1 (#x967), so how does emacs know to use that font? and how come emacs on my new PC doesn't do that?
I'm using emacs 26.2 on both PCs.
What could be the problem?
