Screenshot of broken Japanese text in notepad.exe

Hello, I've installed wine-staging (over wine-stable) and I noticed I'm no
longer able to open Japanese text files with notepad.exe using locale override
LANG=ja_JP.UTF-8

Squares appear instead of Japanese glyphs. I tested with empty wine prefix. I'm
attaching a screenshot of the following text file:
たこ焼き
てすと
ｔｅｓｔ
한국어
æ

I also noticed similar problem in the edit fields of another program.

Expected behaviour:
Default "System" font should display all these characters in one way or
another.

Workaround:
Change font in notepad.exe to one explicitly containing Japanese characters.
