SQLB-2833: Wrong encoding in Gupta.SQLBase.Standard.dll when using with .NET core 3.0

[Uwe van der Horst]

There is a encoding bug in Gupta.SQLBase.Standard.dll Version 12.2.0.12329. When using from a .NET CORE project, special characters (german umlaut) are destroyed when reading strings from the database. No problems with normal .NET project. The reason is that in .NET System.Text.Encoding.Default is iso-8859-1 and in .NET CORE 2.2 and 3.0 System.Text.Encoding.Default is UTF-8.

Test case attached. Create test database with the SQL file and then execute the .NET Core 3.0 project. You see console output with the error.
