Special characters displayed incorrectly in the opportunity description field

Hi everyone!

The description field in the opportunities module is displaying special characters incorrectly. I noticed this problem only in the opportunity description field.
In the notes module, the description field displays the characters correctly and the field type (TextArea) is the same as the opportunity.
The same problem is displayed in this environment: https://suite8demo.suiteondemand.com/

SuiteCRM version: 8.6.2.

Has anyone seen this problem and knows how to solve it?

I think it is bug and also we have same problem in cases module.
