# These are a few representative patterns whose lengths and offsets are to be # shown when the link size is 2. This is just a doublecheck test to ensure the # sizes don't go horribly wrong when something is changed. The pattern contents # are all themselves checked in other tests. Unicode, including property # support, is required for these tests.
