MATLAB: Special character not saved / displayed properly in .m file

Question

I have two versions of matlab: 2013a and 2014a. Just to give an example, lets have a .m file containing:

a = 'Å'

save this .m file in 2014a, reopen, it becomes

a = ' ?'

On the other hand, if you run a = 'Å' in the command window, it works.

For 2013a, saving the file and reopen, there is no problem, it is still correctly displayed as a = 'Å'

Then, if I save the .m file in 2013a with the command a = 'Å', and open in 2014a version, it becomes

 a =  '

This is annoying. Any help is greatly appreciated.

Answer 1

Ok I think I've found out whats going on.

I am using Win 7, and I noticed that the Language for non-Unicode programs was Chinese. Changed to English and it works fine now.

Still don't know why only 2014a ver has this problem though.

Thanks to Guillaume and everyone who helped.
