I installed the Japanese language pack for Windows 8 but I'm finding Japanese folder names and siilar don't have the actual characters displaying, either it has square blocks or garbage like '—ö‚ÍI‚í‚ç‚È‚¢‚¸‚Á‚Æ'
Any ideas how to fix?
It's because your folder names aren't encoded in UNICODE, but SJIS.
Windows, since Vista, has Asian fonts preinstalled by default
You have to change the default encoding for Windows, but this is gonna cause a lot of trouble for all other western applications.
How to do that? (actual wording may change because I don't have Windows in English)
Be warned that most western applications will be affected (for example, even windows explorer will display C:¥windows¥system32 instead of C:\windows\system32)
If the folders are few, it's better to manually recover the name with an encoding converting tool
go to control panel view by large icons search for language click it add language go to options download and install language pack
Windows 8 does actually support unicode in the folder names.
There is no need to change the encoding as mentioned in other answers and there is no need to install additional language packs from the control panel.
You you have to trick windows into loading unicode font support on startup.
You can do this by creating an empty text file on your desktop.
Then rename the file to: 火.txt
Now restart your computer, this will force windows to load the correct font on startup.
You now have japanese font support for filenames.
