           Product: Wine
           Version: 6.10
          Hardware: x86-64
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P2

riched32:editor fails in Wine when run in the Arabic (EG and MA) and Hebrew
(IL) locales:

https://test.winehq.org/data/patterns.html#riched32:editor

editor.c:122: Test failed: [2] EM_GETLINECOUNT returned 2, expected 2
editor.c:122: Test failed: [5] EM_GETLINECOUNT returned 3, expected 3
editor.c:122: Test failed: [6] EM_GETLINECOUNT returned 4, expected 4
editor.c:122: Test failed: [14] EM_GETLINECOUNT returned 3, expected 3
editor.c:122: Test failed: [15] EM_GETLINECOUNT returned 4, expected 4
editor.c:455: Test failed: 1: expected_bytes_written=2
editor.c:455: Test failed: 2: expected_bytes_written=4
editor.c:455: Test failed: 3: expected_bytes_written=5
editor.c:455: Test failed: 4: expected_bytes_written=3
editor.c:876: Test failed: EM_POSFROMCHAR reports x=1, expected 8
editor.c:902: Test failed: EM_POSFROMCHAR reports x=1, expected 8

In both cases the failure are the same. Also the test succeeds in the
corresponding locales on Windows 2004.

The test on line 122 fails because Wine returns the same values in RTL locales
as in LTR ones.
