"t" character repeats after upgrading to SP19/20

I'm working with VS2015, framework 4, and after I upgraded to SP19 or 20 I get a strange behavior.

"t" character is repeated sometimes: the word "lotto" is printed as "lottto" and this is not the only one case.

I do work a lot of time with Calibri font.

This happens both in development environment and in client-side environment. If I rollback the runtime version it works well.

Is an issue you already know?

do you need some test case or are you able to reproduce it?

Thank you

Yes, known issue, use Google Search and you'll find info on usp10 1.6 fixed the issue. Due to an update for framework support and CR using an older version 1.4 of usp10.dll it's going to break.

SP 21 should fix it or possibly use a different font.
