First of all: When using Sybase 12.5 with charset default "utf-8" this issues will not occur.

1. When I try to fetch some data from a Sybase 12.5 server (code page ISO8859-1) I receive a message telling UNICHAR and UNIVARCHAR are only avaliable when server's charset is utf-8. How can I set another codepage or disable utf-8 in nhibernate? (Vs2005 C# + Sybase.Data.AseClient 1.15.152.0). Database and client works fine without nhibernate.

2. When I try to fetch a collection from any table where the primary key is char or varchar I get no results. (same environment)

Any help is very welcome.
