    _______________________________________________________

Details:

Octave print function adds 3 additional spaces proceeding subscript and
superscript regions. This occurs independent of renderer used and output file
format. On screen representation is correct however.

The code below is the minimum reproducible example. Note, the on screen
version looks fine, while the saved image does not.


close all
clear all 
x = -10:10;
y = x.^2+5*x+7;

h=figure()
plot (x,y ,'o')
text (-4,50,"Example Error (mm^{3})")
xlabel("blah blah (unit_{8})")
ylabel("more blah (unit2^{28}_3)")

%occurs independent of graphics_toolkit and output format
print(h, "BugImage.eps","-depsc");


System Info:
GNU Octave, version 4.2.1 configured for "x86_64-redhat-linux-gnu"
Fedora 26 (4.15.3-200.fc26.x86_64)

Let me know if you need any more info
