Yes indeed - in that case, it does work (I removed
/etc/olpc-security). I also noticed that before I removed
olpc-security, I had to set the font manually, now I don't need to do
this. (Some interaction problems between fontconfig and rainbow ??)

The relevant piece of code is in
http://dev.laptop.org/git?p=projects/olpc-utils;a=blob;f=usr/bin/olpc-session;h=473d75dcb214955468ddb74cb2bd76138a02d353;hb=HEAD#l29

Any idea on how we can set the variable so that the activities can use
this properly ? Interestingly though, activities like Browse seems to
handle the composed characters just fine even if security is enabled.


Thanks,
Sayamindu
