- MakeEncoding.cs program pulls from .NET encodings (tested with Windows 7) (outputs stored at dotnet/out and misc/err) - Many new codepages and improvements - coverage + coveralls - better environment handling (h/t @xch89820) - cpexcel.js for the formats recognized by excel - decode endian option removed (implicit from codepage definition) NOTE: utf7 encode can be more space efficient
