The expected results for these test cases are created without the MS Office fonts present. The tests refer to several MS Office fonts: LucidaSansUnicode, MS-Gothic, and Arial Unicode MS. I haven't looked at what is being tested by these tests, but it would be preferable for the test not to refer to these fonts if at all possible.
This test was enabled in r17623 with results created with the MS Office fonts present. In r17639 the results were recreated without the MS Office fonts.

Thanks for filing this bdash. I was aware of the likely failures when I checked them in. It's best to just get these tests "fixed" as best we can so this stops occurring.
As to what's being tested? Simple international text support, iirc.
Disabled the tests for now.
