You show great misunderstanding. AA means ASCIIArt. What
>>21 posted is more like SJIS or Unicode art. And how it looks depends entirely on the font, and is absolutely independent of the character set, as long as it allows you to use these characters.
When you set your browser to SJIS (or it detects a SJIS page), it'll automatically choose a Japanese font, like MS Gothic or MS Mincho. However, they use your preferred fonts for UTF-8 and UTF-16 (Unicode).
The solution to this problem would be to use the MS Gothic font-family in the world4ch stylesheets. Or perhaps just one of them. That way you'll be able to see text art as you want.
