I just started to download Acrobat Reader 5.0, which is free. I used to use Acrobat Reader 4.0 with Japanese supplement fonts. Both of them were provided by Adobe for free.
After I installed the English version of Acrobat Reader 5.0 and its Asian fonts, I was able to read an Asian document that I created last year. See [Figure 6].
