OpenDS2.0 (http://www.opends.org/daily-builds/branch2.0/20090629180000/OpenDS/build.jdk5/package/OpenDS-2.0.0.zip) shows squares instead of non-ascii characters (e.g. chinese) when used with:
1) jdk1.6.0_14 on RHEL (32 and 64 bit). On the same plateform, this is working with jdk1.5.0_15
2) Solaris5.10 x86 with a JDK1.5.0_16
3) other combinations not tested

workaround for solaris:
- cd /usr/java/jre/lib
- mv fontconfig.bfc fontconfig.backup
- mv fontconfig.properties.src fontconfig.properties

workaround for RHEL:
removing all fontconfig.Redhat*, and keeping only one
fontconfig.Redhat.properties.
The path to the japanese TTF files was pointing where there was no such files.
I copied the TTF files where expected to be and it worked fine.
