Thank you all very much!

Doug, your solution worked for me. This is a great relief - thank you!

Dmitri, thank you for the informative explanation and good questions. When I cut and paste "Å" into Octave, nothing appears in the terminal. If I run from a .m file with the character "Å" in the title, it instead prints "Ã..." where "Å" should be.

Doug, how did you find out that [char(195) char(133)] was the combination you needed?
I found it by trial and error and try again through different numbers. I still don't understand how it works!!!
According to the ASCII table I looked up, those two are ├ à. I realized I also need an em dash which would be ASCII character 196, but Octave crashes whenever I try to plot something with char(196) in it.

This isn't as important because I can work around it (since the regular minus is only too small if I use e^{-qd} instead of exp(-qd) - i.e. by writing things without subscripting) but would be nice if there's a simple explanation. If it's not an easy fix, though, don't trouble yourself with it. I appreciate all that you've done already!

These both work in MATLAB, so this sounds like an Octave bug.

BTW, it's also worth mentioning that in LaTeX, \deg is actually an operator:

macro:->\mathop {\operator@font deg}\nolimits

And this is what MATLAB gives you for '$\deg A$'.
