Windows – Japanese Text showing squares on windows 7

Japanese text … does not appear anti-aliased in my browser

Windows doesn't anti-alias fonts below a certain size - I believe this is font specific. Try a different font or try increasing the text size (Ctrl++ in many browsers)

is there a way to ensure a website of my own creation displays anti-aliased Japanese text?

There is no sensible way to achieve this. Your website might be viewed by PCs running a variety of different operating systems with a variety of browsers. Consider phones, pads, tablets, netbooks, TVs and other hardware platforms.

You could pre-render the text as graphics images but this is troublesome to achieve in a way that is readable on both phones and dual-24" screens. It also means your text won't get indexed by search engines and so is likely to rank lower in searches.

Your could use Flash but many of the same disadvantages apply. Not all platforms support Flash and some people disable it.

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)

1. Go to language in control panel
2. Select "change time, date, number format" on the left
3. Go to the "admin options" tab
4. Press the button on the bottom to select which encoding to use with programs that don't support unicode

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
