mozilla-0.7, built at redhat, uses only iso latin 1 fonts in url field and in forms fields. But it have to use fonts in current locale encoding (koi8-r fonts for ru_RU.koi8r locale). The same buggy behavior like netscape 6. With mozilla-0.7 binary from www.mozilla.org everything is OK.
Japanese is hosed too.
Adrian, wasn't this an installer bug?
I've just found that this problem does not happen if LANG is set to full canonical value (ru_RU.KOI8-R). But installer set LANG to ru_RU.koi8r, and mozilla does not work properly with it. As for Ukrainian, it does not supporn neither uk_UA.KOI8-U, nor uk_UA.koi8u. It seems to me that there is somewhere a hardcoded list of supported locales in mozilla. It should be fixed or installer should use mozilla-friendly LANG values.
No, the canonical locale is ru_RU.koi8r -- see: /usr/lib/locale/ru_RU.koi8r/
msw can you file a bug in mozilla's bugzilla about this issue?

Fixed in 0.9.1 which should show up in rawhide shortly.
