8.1.3 - Lost of international characters (é > é)

Since update 8.1.3 international characters are lost when entered in a Perspective text field.
It was working properly on: 8.1.1 (b2020120808)

When entering: “çéâêîôûàèùëïü” (French letters)
The value kept in memory, sent to OPC or recorded in the database is: “çéâêîôûà èùëïü”
String values with international characters already in memory/tag/database are properly displayed, until they are updated. We can avoid the bug by adding value.decode(), but we dont want to review and add complexity to our many projects if the bug is to be fixed soon.

We saw the same bug on two servers after updating their Gateway to 8.1.3 running totally different projects.
