Outlook calendar encoding troubles

[JackSmith]

Hello, writing to you in times of great need

In my organization, users use zoom meetings by creating them via browser. They copy the meeting parameters to a recurring meeting in outlook. And they send this meeting to several people. All good so far

But sometimes they decide to add something (text, files) to a meeting instance. Send a meeting update to all participants. And then boom! When a meeting participant opens the modified meeting in the calendar, he sees it with a corrupted encoding. Everything is ok with meeting update in inbox, problem with calendar.

Here is an example of corrupted text:

С уважением,

of course I can convert this text into readable, but this will not eliminate the problem, but only the consequences

thanks!
