    Apparently this Bug still exists in Unity 2018.3.14 ... still the only thing working is switching to compatibility level ".Net Standard 2.0" ... exception is thrown for

    ```
    var serializer = new XmlSerializer(typeof(SomeType));
    ```

    exception:

    System.ArgumentException: 'CP1252' is not supported encoding name.

    Still had this issue in 2018.3.4f1 with Api Compatibility Level .Net 4.x
    Switching to .Net Standard 2.0 (still throws an exception but) worked for me.

    Seems to be still open for 2018.3.0b6 with .NET 4.6 enabled. I think this should not only be fixed for a specific framework, but for all available frameworks. Could you please reopen this issue so that we can cast votes again?

    @JOSHPETERSON
    I see that 2018.3b was released for beta. However, this issue is not mentioned in the release notes. Is this fixed?

    So which version of Unity is this fixed for IL2CPP?

    Just upgraded to 2018.2.1f1. I confirmed that the System.XML.Serialization issue is fixed under 2018.2.1f1 under the ".NET Standard 2.0" selection in the "API Compatibility Level" setting.

    @joshpeterson - I am currently using 2018.1. Is there a release date for the 2018.3 beta? I am also using System.Xml.Serialization and have the same output as @cruelbob. I am unable to run on iOS and release to my testers because of this error.
