--- Comment #1 from François Gouget fgouget@codeweavers.com --- Note: It is now clear that the test fails whenever the month contains accentuated letters: * December / décembre -> fails * January / janvier -> no accent, succeeds * February / février -> fails
That means there are only 3 months in the year where this test fails: December, February and August. * August / août -> fails
