Find and Replace dialog box show weird characters

We’re seeing the same. Re-built the PC (win 10). Edge still shows the issue.
Same user on a different PC (same AAD login) - good (so far)
Another Edge profile on first PC, different 365 user — BAD
Installed Chrome — occurs there too BAD.
Installed Firefox — doesn’t occur (so far).
Logged into the same PC as another (local) user. — good. (so far)

Also, using browser’s Dev tools, changed the font away from Arial, correct characters appear!

So, affects Edge and Chrome. Not seen in Firefox.
Only affects one user profile on one PC (so far) — reoccurred after a rebuilt.
Only affects Arial.

I’ve put lots of “so far” because, as noted her by other folks, and we’ve seen, that the issue can take time to appear.
