If open_mfdataset() is actually dropping the encoding, then this is an issue related to #1614. That's because in open_mfdataset() while the attrs are explicitly set to those of the first supplied dataset, I don't see any similar explicit treatment of the encoding. I think that means the encoding is being set by what happens inside the core of auto_combine(), and is presumably being lost upon some of the concat or merge operations which happen inside auto_combine().

So I think to fix this then either open_mfdataset() should contain explicit treatment of the encoding, or the rules for propagating the encoding through the auto_combine() should be solidified.
