Test Russian and Hebrew sort

[doktorbro]

Based on #2379 (comment) from @envygeeks

@envygeeks Looks like the test crashes on Ruby 1.9.3 only. Newer versions can handle non-ascii sorting. Can you fix it in 1.9.3?

@penibelst test failed by some different reason (as far as i see) and just needed to be restarted on travis. Other than that I would also propose to test ascii+utf8 edge:

assert_equal ["_вуз", "вуз", "вуз_"], @filter.sort(["вуз_", "_вуз", "вуз"])

No, this is wrong. The test fails on my local machine with Ruby 1.9.3 too.

Ah. indeed. Well the issue is not with spec actually anyway :)) Use following patch to fix it:
