For some strange reason, my computer suddenly doesn't show certain unicode characters anymore! I have no idea what happened.

Affected applications include Windows Explorer (should be Japanese characters), Google Chrome (should be a heart), and Winamp (should be stars):

Russian, German etc. characters are displayed normally. Chrome also displays Japanese script on websites, but not in the GUI. How can I fix it?

TL;DR: A workaround is to put a shortcut with a Unicode name on the desktop so that explorer.exe is the first process to display a Unicode string after booting.

Update: I have tried to use System Restore to fix it. I needed to go back in time quite a while because the most recent restore points didn't solve it so I used one from the middle of November. After that restore, Unicode symbols were displayed again. Then I updated my system with Windows Update again because those were removed during the restore. After that, the error occurred again! I then did a restore to a point before my new updates, but the error persists, and the old restore point (which I used before) is gone and there are currently no other snapshots of the system. Any suggestions on what to do now?

Update 2: I could find a workaround:

Control Panel → Region and Language → Administration → Change Language for Unicode-incompatible programs to Japanese (Japan).

All mentioned programs display their symbols correctly again. However, I don't consider this a fix because these programs are not usually Unicode-incompatible, and it also leads to some (non-serious) artifacts in some programs. I still welcome an answer that tells me what went wrong here and how to fix the issue.

Update 3: I think I have isolated the particular Windows Update which causes the error. It is Slow performance in applications that use the DirectWrite API on a computer that is running Windows 7 or Windows Server 2008 R2. I have installed all other updates except this one, and the error did not occur again.

Update 4: The true origin of this problem was Chrome, see accepted answer. Workaround: put shortcut with Unicode name on desktop so that explorer.exe is the first process to display a Unicode string after booting.

Found this interesting tidbit. It seems that this may have something to do with which application first tries to display a unicode character.

Long story short, I found this bug for Chromium and a comment in the discussion suggests that this is the case and provides a workaround of putting a unicode-named file on the Windows desktop to force Windows to be the first application to render a unicode character:

"Therefore, as a workaround for this issue, put a file named 火.txt or similar on your Windows Desktop. I suppose this causes Windows Explorer to be the first program to render a [unicode] character."

I tried this approach and sure enough, it worked for me -- without having to change the Language for Unicode incompatible programs."

  1. Change your "Language for Unicode incompatible programs" to Japanese (any other language will do)
  2. Change this back to the original value.

It fixed the issue I had with the display of Chinese characters after a Windows update.
