Hi,

I have WinXP. My Browser is a german Firefox,
and I want to see the japanese chars on the website ...

When going to the Firefox "menu bar" . . .
/menu bar/view/character encoding/east asian/japanese iso2022
/menu bar/view/character encoding/east asian/japanese shift_Jis
/menu bar/view/character encoding/east asian/japanese1 EUC-JP

and chosing one of the three options above

I cannot see japanese chars (because there are only non human readable boxes with numbers inside). -How can I get Firefox showing japanese chars correctly?
