Problem Unicode Data 0x2300 In SQLServer 2000 SQLServer 2005 Express

Hi experts;
I have a problem with unicode character 0x2300
I created this table
create table testunicode (Bez nchar(128))

Insert Data
insert into testunicode (Bez)values('Œ€„¢')
with 2 Unicode characters
Œ€ = 0x2300
„¢ = 0x2122

Selecting the data
select Bez from testunicode
I see
"?„¢"

„¢ = 0x2122 is ok but instead of 0x2300 there is 0x3f

When I modify the insert statement like that ( 8960 = 0x2300 )
insert into testunicode (Bez)values(NCHAR(8960)+'„¢')

and select again voila i see
"Œ€„¢"
Does anyone have an idea?

Thanks
