We don't support Unicode as client side. We support Unicode at server
side. What does it mean? You can write and read nvarchar from/to
database however your data will be converted to a client charset. For
example you can use UTF-8. Data are converted from server ASAP so even
using binary binding you get them using charset you provide.
Honestly I don't see any reason to support client Unicode...
