gdiplus: Test for CharacterRange.

[Dan Kegel]

Hi Adam,

seems to trigger a valgrind warning in your test code.

+ Conditional jump or move depends on uninitialised value(s)

+    by  winetest_ok (test.h:304)
+    by  test_characterrange (stringformat.c:67)
+    by  func_stringformat (stringformat.c:87)
+    by  run_test (test.h:452)
+    by  main (test.h:501)
+  Uninitialised value was created by a stack allocation
+    at  test_characterrange (stringformat.c:53)

Could you have a look?

Thanks,
