Fix error when script is in a folder containing special characters

[martinarielhartmann]

Thanks for developing and maintaining this amazing mode, I use it all the time. But I have an issue: my Matlab scripts often need to be in a folder containing umlauts in its name, and so I am unable to run blocks of code without having to paste into the command window. I was wondering, would it be possible for you to fix this issue? Example:

>> emacsrunregion('/Users/johndoe/umlut/script.m',1,13)
Error using emacsrunregion (line 26)
You must save your region into a file accessible by MATLAB process.
 
>> pwd

ans =

    '/Users/johndoe/umläut'

On a related note, I cannot cd to that folder from the command window (but I can if I run the line from a script):

>> cd('/Users/jonhdoe/umlaut')
Error using cd
Unable to change current folder to '/Users/jonhdoe/umlaut' (Name is nonexistent or not a folder).

Tested in R2024a, Emacs 31.

Thanks for your help!

Hi

I am usually not a huge fan of having non ASCII chars in directories or file names, I am on Linux and use detox, to get rid of those.
Since I am using matlab bascially always from Emacs, are non ASCII symbols, in filename and directories supported by Matlab itself.
And if so, since when?
I am currently running into a problem with non ASCII chars in frprint, from the matlab-shell, which I will report soon.
@john @eric what do you say?

I think this is related to issue #25 in that somehow the coding system isn't right, but I'm not sure how to fix it.
