When a java GUI program tries to display Asian characters (e.g. Chinese) without specifying the exact font, they show as rectangles, even though I have suitable fonts installed. A workaround is to create the $JDK_HOME/jre/lib/fonts/fallback directory, and copy/symlink a font file that should be used as a fallback, such as Cyberbit.ttf (which has a wide range of unicode characters). But I think a proper solution should involve fixing the fontconfig files from $JDK_HOME/jre/lib - first, it's not clear which ones are being used; second, I checked all fontconfig*properties.src, and none of them has any correct path for a big5 font (for example). Most of them try to reference ukai.ttc, uming.ttc or bsmi00lp.ttf but the paths are wrong. All these files are in /usr/share/fonts/arphicfonts (and come from the arphicfonts package) but the fontconfig files try to find them in /usr/share/fonts/cjkuni* or /usr/share/fonts/chinese/TrueType or /usr/share/fonts/truetype/arphic. And I'm sure the other Asian fonts (Japanese, Korean etc) have the same kind of problem. Even after fixing the fontconfig files, I think setting up a fallback font could still be useful, in case some fonts are not installed.

This should be fixed in icedtea-bin-6.1.10.4-r1.ebuild icedtea-bin-7.2.0-r2.ebuild icedtea-6.1.10.4-r2 and icedtea-7.2.0-r2 Thanks for the report.
Same problem with dev-java/icedtea-6.1.10.4-r3
Still the same with icedtea-bin-6.1.12.4, why? It should be a simple fix.
If it's a simple fix, why don't you provide a patch?
To clarify, I can confirm that it still doesn't work on 6 but it does work on 7. Andrew would know better than anyone whether this is a simple fix so unless you can prove any different, I'm going to close this as fixed given that it works on 7 and we're planning to phase out 6.
(In reply to Andrew John Hughes from comment #5) > If it's a simple fix, why don't you provide a patch? Mainly because I'm not familiar with the fontconfig files in the jre - which ones are editable and how they are structured, and which ones are generated and how to generate them. The fix would be simple for somebody who knows these things. By the way, I currently have 4 jvm's installed on this computer: - icedtea-6.1.13.5-r1 - buggy - icedtea-bin-6.1.13.5 - buggy - icedtea-bin-7.2.5.3 - ok - oracle-jdk-bin-1.8.0.25 - ok I can accept that the bug is fixed because icedtea-bin:7 is fiiinaly stable (I guess you had to wait for java 7 to be officially declared dead first?) I wonder if the fontconfig files can be copied from icedtea 7 to icedtea 6.
(In reply to aditsu from comment #7) > I can accept that the bug is fixed because icedtea-bin:7 is fiiinaly stable > (I guess you had to wait for java 7 to be officially declared dead first?) More like you had to wait for the Gentoo Java team to come back from the dead. Vital signs are still bad. > I wonder if the fontconfig files can be copied from icedtea 7 to icedtea 6. The fontconfig.Gentoo.properties files from icedtea-bin 6 and 7 are exactly the same. Andrew tells me that 7 doesn't actually need these files but we install them anyway.
Yeah, 7 uses fontconfig as it should. The files are just for fallback if there is an issue with fontconfig, I believe. I'm not really that up on these files either. I thought you might have an advantage over me in having a better understanding of the problem, as I don't tend to make use of characters outside Latin-1. Looking at fontconfig.Gentoo.properties.src, I'm guessing lines like: filename.AR_PL_ShanHeiSun_Uni=@GENTOO_PORTAGE_EPREFIX@/usr/share/fonts/uming.ttc filename.AR_PL_ZenKai_Uni=@GENTOO_PORTAGE_EPREFIX@/usr/share/fonts/ukai.ttc just need fixing with the right path. Files like this have to be maintained in step with the font files they reference and this file probably hasn't been updated in years. It should actually really be in the JDK itself, but it's easier to maintain it in Gentoo itself, I'd say.
Figured it out. In my case, I didn't have arphicfonts installed as I hadn't enabled the cjk flag. 7 must have used some other font. But even after installing that, I realised that the paths for this font package was wrong: # media-fonts/arphicfonts filename.AR_PL_ShanHeiSun_Uni=/usr/share/fonts/uming.ttc filename.AR_PL_ZenKai_Uni=/usr/share/fonts/ukai.ttc Should be: # media-fonts/arphicfonts filename.AR_PL_ShanHeiSun_Uni=/usr/share/fonts/arphicfonts/uming.ttc filename.AR_PL_ZenKai_Uni=/usr/share/fonts/arphicfonts/ukai.ttc Now it works. I'm about to commit a new version of icedtea so I will include this fix and the next icedtea-bin will reprefixify the file installed by icedtea rather than maintaining a separate copy.
