なんか動きがFireFoxIEで違うそうだ・・・詳しくは理解出来ない・・・

I’ve found a discrepancy between IE and Firefox that I think is worth noting. Most of the time this isn’t an issue but most web-pages decode Unicode inputs, so the fact that Firefox automatically encodes every GET parameter with Unicode is not a big deal. However, if the page doesn’t do any conversions, but rather echos the data back exactly as it was seen Firefox isn’t vulnerable. However, Internet Explorer is - because it doesn’t convert " into %22 for instance.
