Greek letter issue with debugger

[gregmoille]

Describe the bug

Error with encoding on windows when using the debugger and greeks letters. Might need to write the letter in Latin alphabet instead to fix it

To Reproduce

Need to set the debug option to True on Windows

solver = pyLLE.LLEsolver(sim=sim, res=res, debug=True)
solver.Analyze(plot=True, plottype='all')
solver.Setup() 

Expected behavior

No error while setting up everything

or send an email to the mailing list at ipython-dev@python.org

You can print a more detailed traceback right now with "%tb", or use "%debug"
to interactively debug it.

Extra-detailed tracebacks for bug-reporting purposes can be enabled via:

Desktop (please complete the following information):

• OS: Windows

Quick fix

Set the debugger to False:

solver = pyLLE.LLEsolver(sim=sim, res=res, debug=False)

What's the motivation for the greek letters in the first place? It seems odd to use them, because most people (mysef included) have no idea how to type a gamma on the keyboard...

[gregmoille]

Well... there was literally no real reason to be honest and I went down the rabbit hole to make it prettier with greek letter and that turned into a whole issue. I think with the translator that is coded in the main python file, it doesn't matter, one could either use the "latin" version of the letter (gamma, kappa, etc...) and it should all be automatic. If you notice in the core I actually don't use the greek letter and this is only for the interface so technically we don't need them.

[DanHickstein]

Ha! Okay, I was curious. I had never seen greek letters in code before :). It does give the examples a distinctive look!

[gregmoille]

Interestingly people coding in Julia use a lot of non-standard UTF8 characters, with like the ½, underscript letters, and greek letters. I gave it a shot didn't think python would accept it but was curious that actually, python doesn't even care, even emoji work apparently.

even emoji work apparently.

What?!? This is the best thing that I've learned this month 😊.
