Firefox will display a small square with 4 digits instead of the corresponding unicode character. You can see what I mean in the image on the URL. Additionally, I didn't find any related USE flag to change: [ebuild R ] net-www/mozilla-firefox-1.0_rc2 -debug +gnome +gtk2 -ipv6 +java -ldap -mozdevelop -moznoxft -mozxmlterm +truetype -xinerama -xprint I don't think any of them are related to utf-8.

You need to install japanese fonts in X. Then firefox will display the characters. USE="nls cjk" emerge xorg-x11 kochi-substitute Then restart xfs and X
Thanks for the tip, Matt.
