Problems with decrypting columns

Hi!

I want to encrypt a whole column in my table and I do this with this SQL code:

OPEN symmetric key Sym_Key DECRYPTION BY certificate My_Cert
GO

UPDATE [My_demo].[dbo].[My-DemoList]
SET [Test_crypt] = encryptByKey(Key_GUID('Sym_Key'),[Test])
GO

CLOSE all symmetric keys

GO

And this seems ok but when I want to decrypt it with the view I have created it seems that I get a "rubbish" character between each "real" character.

So my questions is: What am I doing wrong

Because if I do an insert like this

OPEN symmetric key Sym_Key DECRYPTION BY certificate My_Cert
GO

INSERT INTO [My-DemoList] (Test_crypt) VALUES(encryptByKey(Key_GUID('Sym_Key'),'1234567'))

GO

CLOSE all symmetric keys

And then use my view to look at the decrypted value that I put in its ok.

Many thanks in advance!
