I've been trying to print out the degree sign on the screen. Im using myriad Pro font from the device and using the bbutil_render_text function to display it. I've tried using \176 (ansi) and \u00B0 (unicode) codes but they print ~ and some garbage respectively. any ideas?
this is a common behaviour based on the fact, that bbutil only loads standard ascii characters (first 128 chars).
Therefore you need to write your own render text, update the bbutil or use a char with a ascii code < 128
