Alas, this is a known issue.  The 'tex' interpreter for OpenGL only exists for on-screen rendering, not for printing.  Marking this bug as a duplicate of bug #42320.

Here is an example of the behavior:

close all;
graphics_toolkit('fltk');
figure(1);
plot(1:10);
title('\bf Hello');            % bold
xlabel('angle [°]');           % special character
text(1,8,{'line 1','line 2'}); % new line
print('-dpng','image.png');

The resulting png file has neither

  • the bold print of the heading, nor
  • the new line of the text object, nor
  • the degree sign in the label

This happens with fltk. In Gnuplot its a bit better, at least the linebreaks work there. It works totally fine in Matlab.
