The unicode object IS subscriptable. It is a unicode string which has 
characters.
The value None is not subscriptable. It probably means that you have a 
NULL value in your database.
Try the following:

def   nulltoemptystr(value):
    if value is None:
       return "<EMPTY>"
    else:
       return value[:10]

print template % (ID, IID, nulltoemptystr(Function), nulltoemptystr(Description),ErrorNumber, StatusCD)


You can also try to do the same in SQL. For example, this works with 
FireBird, PostgreSQL and many others:

select coalesce(Function,"") as Function from TableName

instead of

select Function from TableName

But first of all, I would recommend you to go over the Python tutorial. 
It explains these things and more.
