Some web pages may require additional fonts to display properly.
Try installing some of the following packages if some characters
are not displayed properly:
- media-fonts/arphicfonts
- media-fonts/bitstream-cyberbit
- media-fonts/droid
- media-fonts/ipamonafont
- media-fonts/ja-ipafonts
- media-fonts/takao-fonts
- media-fonts/wqy-microhei
- media-fonts/wqy-zenhei

Depending on your desktop environment, you may need
to install additional packages to get icons on the Downloads page.

For KDE, the required package is kde-frameworks/oxygen-icons.

For other desktop environments, try one of the following:
- x11-themes/gnome-icon-theme
- x11-themes/tango-icon-theme
