How to make NHibernate and nvarchar2 friends?

Question

Oracle

I need to write/update a unicode string to an nvarchar2 field using NHibernate, but NHibernate doesn't add an N prefix to this field, which causes the string to not be considered unicode.
Has anyone encountered a similar problem and how to solve it?
