Steps:
1. Setup the following FontLink registry:

[Software\\Microsoft\\Windows NT\\CurrentVersion\\FontLink\\SystemLink]
1208451304
"MS Sans Serif"=str(7):"simsun.ttc,SimSun\0gulim.ttc,Gulim\0msgothic.ttc,MS UI
Gothic\0mingliu.ttc,PMingLiU\0"
"Tahoma"=str(7):"simsun.ttc,SimSun\0gulim.ttc,Gulim\0msgothic.ttc,MS UI
Gothic\0mingliu.ttc,PMingLiU\0"

Ensure you have these fonts: simsun.ttc, gulim.ttc, etc. or change the values
with proper font name. This gets the CJK fonts display properly.

2. Run winecfg, change Menu Text font to Tahoma 8:

3. Run notepad on zh_CN.UTF-8:
$ LANG=zh_CN.UTF-8 ./wine programs/notepad/notepad.exe.so
wine: Unhandled page fault on read access to 0x0016885c at address 0x7e493aca
(thread 0009), starting debugger...
WineDbg starting on pid 0008
Unhandled exception: page fault on read access to 0x0016885c in 32-bit code
(0x7e493aca).

See attached bt.txt.


A regression testing shows the following commit:

$ git bisect bad

    gdi32: Remove the code which bypasses the DC transformation checks.

    If it's absolutely required to check the child list first, that should be
    done inside of find_in_cache using the same comparisons as done there.
