: that aren't available in that font.
: On OS/2, we take the charset that we are passed with the page and convert
: the entire page to that native charset and display it - we don't display
: anything in UTF-8. So when you view a Russian page, we convert the Unicode
: that Mozilla sends us into Win1251 and display it. We have tried displaying
: everything in UTF-8, but it does not work. The reason is because most OS/2
: fonts do not support UTF-8, so you just get junk. We would have to display
: every page in Times New Roman MT 30.
: You're next question is probably "If you get the charset, why not just
: display page with the utf-8 charset tag in the UTF-8 codepage and use Times
: New Roman MT 30?" The answer to that is that when Mozilla gives the page
: to the font engine, it tells us that UTF-8 pages are in Western. There is
: no way for us to know at the font end that a page is actually a UTF-8 page.
: So we treat UTF-8 pages as western because we don't know any better.
: We are very open to suggestions on this. This particular problem is
: probably the biggest Warpzilla problem at this time.
