I can't find option(s) directly to set UTF-8 rellated Collations/Charsets in SQL Server 2005/2008, same as is possible to set in another SQL engines, but in SQL Server 2005/2008 are there only Latin and SQL collations.

Is there some option to force/install these collations / charsets in SQL Server engine (for both ver.) 2005/2008 on Win2008 OS

No, there isn't. SQL Server doesn't support UTF-8.

You need to define your columns as nvarchar/nchar if you want unicode data. Note, internally SQL Server stores this as UCS-2.

Note that this has ben requested from MS on Connect and there is an older KB article. And some info on this blog too

additionally, if you're going to be doing any text matching on an nvarchar with foreign characters, you need to match on a string formatted with an N before the string (e.g. N'οἰκονόμον'). – swasheck Mar 9 '12 at 17:31
Has this behaviour changed in any recent release of SQL server? – Seiyria Jan 28 at 19:54
@Seiyria: no, same behaviour – gbn Jan 29 at 7:34

You can't install UTF-8 as a character set because it's not a character set, it is an encoding.

If you want to store Unicode text you use the nvarchar data type.

If you want to store text encoded using UTF-8, you store it as binary data (varbinary).
