ROS Rviz TEXT_VIEW_FACING Marker
How to change the font in rviz markers, and make it support unicode?
TODO insert github issue
Have rviz cloned in tmp_catkin_ws, can source devel/setup.bash, but it seems like some portions of the system installed rviz are still being used?
Changing the fontName in ogre_helpers/movable_text.h header did not change the font. Just hardcode into movable_text.cpp constructor setFontName().
The default Arial font was really /usr/share/fonts/truetype/msttcorefonts/Arial.ttf?
Other fonts in that directory:

Try Courier_New- no that results in exception.
The font is actually in /opt/ros/jade/share/rviz/ogre_media/fonts/, which contains arial.fontdef arial.ttf font_arial.png. I can see some unicode characters in font_arial.png
TODO show font_arial.png
But are they at the right index?
There are 18 characters per row, and the degree symbol is on the 8th row, 16th column- no thee number of columns varies, cannot find the index like that.
Want to use the degree symbol which is u00b0, on linux gnome terminal and vim press ctrl+shif+u, then type 00b0: °. 0xb0 = 176
Try altering the png and running rviz. Altering it in the tmp_catkin_ws ogre_media dir did not work. Next try the opt location- no change.
Maybe can alter the ttf file and see if that causes a change, or copy in a different ttf- probably needs a fontdef with it? Only other fontdef is in Gazebo fonts /usr/share/gazebo-5.0/media/fonts .
