Unicode Problem: Which Collation SuiteCRM uses?

When I was in the configuration steps, a message appered:

SuiteCRM Step 2 of 2 - Configuration

Creating SuiteCRM configuration file (config.php)

Creating SuiteCRM application tables, audit tables and relationship metadata

Creating default SuiteCRM data

SQL Error : Unicode data in a Unicode-only collation or ntext data cannot be sent to clients using DB-Library (such as ISQL) or ODBC version 3.7 or earlier.

Why the documentation did not aproach this information? Nor MSSQL database Collation, neither Unicode Configuration to database.

It´s a little helps! So, I think this issue is unicode collation configuration, how to fix this?
