If you're using WinXP, you can enable Complex Scripts and East Asian Language support under Regional and Language Options in the Control Panel

Now when you pick a font in a program, any with a name beginning with "@" should contain a fair number of the symbols, but sideways - just remove the @ in front to get the version of the font with the symbols the correct way round
If you want more fonts, then off the top of my head, hongfire.com might be one place to check to find torrents of large batches of fonts with asian support, though I haven't checked recently so don't know if there's any current alive torrents for them or not
