What will stop working in Bitrix if you set mbstring.func_overload=0?

Question

1C-Bitrix

If you set mbstring.func_overload=0, then installation or restoration using the restore.php file will stop working in Bitrix. This can be sacrificed, it is not often needed.
What else will break?

Answer 1

You will get encoding problems. If your site was originally created in UTF-8, then you will have problems with language phrases, so-called bugs will appear, and in the public part, problems with encoding components will also begin

Answer 2

Visual editor, component customization, some other things.
It is better to set mbstring.func_overload=0 only on the folders you need.
