SQL Server 2008 :: Trying To Print Records That Have Only English Characters

I have a small table that looks like this

create table Test(ID number, Name nvarchar(500));
insert into Test(1,'abc testing');
insert into Test(2,'abc include persian آنا اسمیت');
insert into Test(3,'mnp testing');
insert into Test(4,'abc include Russian Джон Тед');

I want to get records that have only english characters i.e ID=1 and 3 only.

I tried select * from Test where Name like '%[a-zA-Z0-9]%' but this will return all 4 records. How can I accomplish this?
