Japanese character are saved as question mark in SQL Server

I'm working on SQL Server 2005, in which I have a database. When I use Japanese Characters in my application, they are stored as question marks in the databse. I would like to which Collations should I use save the japanese cha开发者_JAVA技巧racters properly.

Note: Additional info(if it helps) In MySQL, we have used UTF8 as default character set in the startup variable and it works file.

Thank you,

Pavan

Japanese_90 appears to be the new collation name.

Note, you might want to consider the _KS suffix if you want to consider Hirigana/Katakana whilst sorting. Like Marc_S says, you will also want to ensure your column datatype is nvarchar
