Connection problem to Informix from SQL Server 2005 with Unicode data

I have Informix 9.4TC6 and SQL Server 2005.
DB_LOCALE in Informix DB is en_US.utf8 (en_US.57372).

First, I created DSN to Informix. Then tried to get data with WinSql
tool and it works fine.
But when I created linked server in SQL Server 2005 I have problems
with languages other than English.
I get a string like:
=E8 '=E5=B7 =E5=8C-=E5|=E5=B7=A5=E6=A5=E6 =AA=E51/4 =E41/4=9A=E7=A43/4

It seems to me that SQL Server splits 2-byte characters in 2 1-byte
characters.
If in options of linked server we set Collation Name to exact
language
we want --> then string data will be correct (of course only of
language that we choose).

Do you have any suggestions?????????

P.S. I don't want to use SSIS (DTS) for extraction from Informix DB

I found a solution.

I found a solution.

SQL Server uses UCS-2 encoding, but Informix Database Server - UTF-8.
And I tried different ODBC and OLEDB drivers and they didn't
converted
from one encoding to another.
But, I am lucky :), I found a solution. I am using CLR possibilities
of SQL2005 and created a function that converts data from one
encoding
to another (http://msdn2.microsoft.com/en-us/library/ms160893.aspx).
