Cant use embed, UTF-8 is not a supported encoding name

trying to embed a Youtuve video in the RTE, this error happens:

Cannot read content as string using an invalid character set. ---> System.ArgumentException: '"UTF-8"' is not a supported encoding name.

I have applied a custom Utf8 encoding provider (in a IComponent Initialize) I found somewhere (could not remember where, neither understand under the hood but hope someone here can input more to make it more clear)

public void Initialize() { Encoding.RegisterProvider(new CustomUtf8EncodingProvider()); }
```
public class CustomUtf8EncodingProvider : EncodingProvider
{
    public override Encoding GetEncoding(string name)
    {
        return name.InvariantEquals("utf-8") ? Encoding.UTF8 : null;
    }

    public override Encoding GetEncoding(int codepage)
    {
        return null;
    }
}
```

So I have added this but it doesn't seem to be running this code

 public class InitializeEncoding : IComponent
    {
        // initialize: runs once when Umbraco starts
        public void Initialize()
        {
            Encoding.RegisterProvider(new CustomUtf8EncodingProvider());
        }

        // terminate: runs once when Umbraco stops
        public void Terminate()
        { }

    }

    public class CustomUtf8EncodingProvider : EncodingProvider
    {
        public override Encoding GetEncoding(string name)
        {
            return name.InvariantEquals("utf-8") ? Encoding.UTF8 : null;
        }

        public override Encoding GetEncoding(int codepage)
        {
            return null;
        }
    }

I forgot to note that it is a IComponent and then must be registered through a IUserComposer, e.g.
```
public class SiteComposer : IUserComposer
{
    public void Compose(Composition composition)
    {
        composition.Components().Append<InitializeEncoding>();
    }
}
```

I do not know, I cannot explain. It is a weird issue, but see that it just happens to a small number of Umb site (not much report about this issue).
