Title: sqlsrv UTF-8 changes

Currently the sqlsrv driver doesn't properly support UTF-8 characters e.g. the Chinese characters for China (中国) unless you N prefix all strings to be N'string'. I am fairly certain this is harmless and a [question to stack overflow](http://stackoverflow.com/questions/7703192/sql-server-nvarchar-n-prefix-for-varchar-fields) concurred with this.

I have modified the value function to add the N prefix.

Please ignore the further change I made to the value function as it is purely a fix for CakePHP 1.2 compatibility.
