UnicodeEncodeError while installing ROS on Debian

edit

Hi all,

I am trying to instal ROS hydro on a Debian system following the guide on the wiki. When I executed:

./src/catkin/bin/catkin_make_isolated --install --install-space /opt/ros/hydro

I got this error:

==> Processing catkin package: 'catkin'
Makefile exists, skipping explicit cmake invocation...
==> make cmake_check_build_system in '/root/ros_catkin_ws/build_isolated/catkin'
==> make -j4 -l4 in '/root/ros_catkin_ws/build_isolated/catkin'

<== Failed to process package 'catkin':

Does anybody know what to do here?
