Fix error when script is in a folder containing special characters

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!
