# There are two sorts of patterns in this test. A number of them are
# representative patterns whose lengths and offsets are checked. This is just a
# doublecheck test to ensure the sizes don't go horribly wrong when something
# is changed. The operation of these patterns is checked in other tests.
#
# This file also contains tests whose output varies with code unit size and/or
# link size. Unicode support is required for these tests. There are separate
# output files for each code unit size and link size.
