First, I don't think there is a problem with the PCRE library in Ubuntu
12.04. It should already have UTF-8 support compiled in, if you have
installed packages from the official archive.

Next, the error message you are seeing is not coming from Octave, it's
from the glib library, which probably means it is coming from your Java
runtime. What version of Java are you running?
