On other Windows build farm animals it is already skipped because they don't use UTF-8 encoding. On "hamerkop", UTF-8 is used, and then the test fails. It is not clear to me (a non-Windows person looking only at buildfarm evidence) whether Windows is less sophisticated than other OSes and doesn't know how to downcase Turkish İ with the standard Unicode database, or if it is more sophisticated than other systems and uses locale-specific behavior like ICU does. Whichever the reason, the result is the same: we need to skip the test on Windows, just as we already do for ICU, at least until a Windows-savvy developer comes up with a better idea. The technique for detecting the OS is borrowed from collate.windows.win1252.sql. This was anticipated by commit c2e8bd27, but the problem only surfaced when Windows build farm animals started using Meson.
