[PATCH 2/2] user32: Enable IsDialogMessageA() ASCII to Unicode mapping only when the user default lang ID is CJK.

[Zhiyi Zhang]

From: Zhiyi Zhang

Using GetSystemMetrics(SM_DBCSENABLED) may incorrectly enable ASCII to Unicode mapping in mixed
locale environments. For example, when UserDefaultLCID is French(040c) but SystemDefaultLCID is
Japanese(0411).

Hi,

It looks like your patch introduced the new failures shown below.
Please investigate and fix them before resubmitting your patch.
If they are not new, fixing them anyway would help a lot. Otherwise
please ask for the known failures list to be updated.

The tests also ran into some preexisting test failures. If you know how
to fix them that would be helpful. See the TestBot job for the details:

The full results can be found at:

[Zhiyi Zhang (＠zhiyi)]

I tested the fix on all of the TestBot variants now. See https://testbot.winehq.org/JobDetails.pl?Key=137901
