[PATCH 0/1] MR7506: kernel32/tests: Add broken in test_IdnToNameprepUnicode.

[Bernhard Übelacker (＠bernhardu)]

Currently test patterns show a systematic failure up to Windows 10 1607. https://test.winehq.org/data/patterns.html#kernel32:locale

As far as I see do these older Windows versions not normalize out the codepoint `U+2066`, [which got added in Unicode 6.3 in 2013](https://codepoints.net/U+2066).

A testbot run [with this patch is here](https://testbot.winehq.org/JobDetails.pl?Key=151649).

In [this testbot run](https://testbot.winehq.org/JobDetails.pl?Key=151647) is another variant of the patch specifying the whole broken string, maybe this is to be preferred?

[PATCH 1/1] kernel32/tests: Add broken in test_IdnToNameprepUnicode.
