Yes, this is probably related to the netCDF4-python change discussed here: https://github.com/Unidata/netcdf4-python/issues/388

Unfortunately, lots of older netCDF programs don't know how to interpret the netCDF4 "string" dtype -- and to be honest, even the netCDF-C library doesn't always properly save such data as Unicode yet, though that should be fixed in the next release (4.4.0 -- see https://github.com/Unidata/netcdf-c/issues/127 for more details).

So an alternative choice would be to attempt to always encode unicode (str on Python 3) attributes as ASCII when saving with netCDF4, e.g.,

python def maybe_encode(string, encoding='ascii'): try: return string.encode(encoding) except UnicodeEncodeError: return string
