russian collation

Hello,

I use Russian localization and would like to change Category.Categories to 'Каталог'.
So, I have executed this code:

UPDATE dbo.Nop_LocaleStringResource
SET ResourceValue = 'Каталог'
WHERE LocaleStringResourceID = 10666

The appropriate row has been updated.
But instead of letters I can see only ????????.

Please help me to solve this problem.

PS: Russian collation on server.

I have found my mistake.
It is necessary to use Nvarchar.

The code should be:
UPDATE dbo.Nop_LocaleStringResource
SET ResourceValue = N'Каталог'
WHERE LocaleStringResourceID = 10666
