I'd like to use Unicode characters in comments in a MATLAB source file. This seems to work when I write the text; however, if I close the file and reload it, "unusual" characters have been turned into question marks. I guess MATLAB is saving the file as ASCII.
Is there any way to tell MATLAB to use UTF-8 instead?
According to http://www.mathworks.de/matlabcentral/newsreader/view_thread/238995
feature('DefaultCharacterSet', 'UTF8')
will change the encoding to UTF-8. You can put the line above in your startup.m file.
How the MATLAB Process Uses Locale Settings shows how to set the encoding for different platforms. Use
feature('DefaultCharacterSet')

As I found solution which worked in my case I want to share it.
Mathworks advises here to use slCharacterEncoding(encoding) in order to change the encoding as desired, but for the OSX this does not solve the issue exactly as the feature('DefaultCharacterSet') in accepted answer does not do it. What helped me to get the UTF-8 encoding set for opening and saving .m files was the following link on MATLAB answers:
https://www.mathworks.com/matlabcentral/answers/12422-macosx-encoding-problem
Matlab seems to ignore any value set in slCharacterEncoding(encoding) or feature('DefaultCharacterSet') but uses region set in System Preferences -> Language & Region. After checking which region is selected in our case then it is possible to define the actual encoding in the hidden configuration file in
$matlabroot/bin/lcdata.xml
This directory can be opened by getting to the Applications and after right click on Matlab by selecting Show Package Contents as on screenshot (here in German)
For example for German default ISO-8859-1 it is possible to adjust it by changing the respective line in the file lcdata.xml:
<locale name="de_DE" encoding="ISO-8859-1" xpg_name="de_DE.ISO8859-1">
to:
<locale name="de_DE" encoding="UTF-8" xpg_name="de_DE.UTF-8">
If the region which is selected is not present in the lcdata.xml file this will not work.
Hope this helps!
The solution provided here worked for me on Windows with R2018a.
In case link doesn't work: the idea is to use file matlabroot/bin/lcdata.xml to configure an alias for encoding name (some explanation can be found in this very file in the comments):
<codeset>
<encoding name="UTF-8">
<encoding_alias name="windows-1252" />
</encoding>
</codeset>
You would use your own value instead of windows-1252, currently used encoding can be obtained by running feature('locale').
Although, if you use Unicode characters in help comments, the help browser does not recognize them, as well as console window output.
For Mac OS users, Jendker's solution really helps!!! Thanks a lot first.
Recap here.
Check the default language in Matlab by typing in the command window getenv('LANG'). Mine returned en_US.ISO8859-1.
In the Application directory find Matlab, show its package contents. Go to bin, open lcdata.xml as an administrator, locate the corresponding xpg_name, in my case en_US.ISO8859-1. Change encoding in the same line to UTF-8. Save it.
Restart Matlab, and it's all done!

I want to use a package called "ESC" elliptic surface calculator that can be uploaded with Maple.
The instructions from the creator are:
Save as a text file with character encoding ISO-8859-1 (ISO Latin 1)
and load within Maple using "read" command).
I have problem with uploading to Maple and saving with this encoding. Can anybody say the exact upload command with details and how to save text with this encoding?
Here is the package page: http://c-faculty.chuo-u.ac.jp/~kuwata/2012-13/Maple_resources/ESC.mpl
I use Windows 8.1 and Maple 18. Thanks!
On the webpage, just right click on the source code file and then click save as a text file.
After that, open maple work sheet and read the file ESC.mpl.txt, like this
restart:
read("C:/tcdata/ESC.mpl.txt") # I have save the file in a folder named `tcdata` in drive C.
Once the file is loaded/read in maple, you can do whatever you are suppose to do. I tried these, to check whether the source code is working or not.
ESC();
elliptic_surface(1,1,1,1,1);
Apparently, the source file has been read and is working properly.
I am on working most of the time on Mac. I have changed the "Text file encoding" of my Eclipse instance from "Properties->Workspace" to UTF-8. But still, when I create EMF model instances (be it dynamic or from registered examples), the created *.xmi-files have always "ASCII" as their encoding. When I try to share these project containing the models, instances etc. over SVN, this causes some problems if I work with these later on a Windows machine. It is probably a Windows problem regarding the SVN. The exact error code can a later post here.
Still, from now on, I would like to work with UTF-8 anyways. So the question is, why are my created text files still encoded in ASCII, even though my Eclipse workspace property has been set to UTF-8?
I have also tried to change the property globally within eclipse.in with the following line: -Dfile.encoding=UTF-8
Another thing I was wondering, if the "New text file line delimiter" from "Properties->Workspace" set to default (in my case Unix) could have anything to do with this issue?
Thank you!

Is there a way of saving the currently running script in Matlab? I have a script which automatically takes a backup of a set of scripts although if I have changed the current script then the saved version will be out of date.
Perhaps its possible to call some java?
Thanks
Somewhere on Yair Altman's site (see link in my other answer) he also referred to a blog entry about editorservices, which was introduced with MATLAB R2009b.
editorservices.getActive().save
should do what you want.
Okay, all I write here I learned from undocumentedmatlab.com by Yair Altman, in particular by looking into his EditorMacro.m... great stuff!
I'm assuming that Itamar Katz understood you correctly and that you are running unsaved code from the editor by using "Evaluate Cell" or "Evaluate Selection"; you want your code to realize that it is not saved and save the version currently displayed in the editor to some other location.
I have not found a way to save the file directly to the original location, but at least I have found a way to access the current text. You can then use fprintf to save it to wherever you want. I have tested this in Matlab 7.11 (R2010b); if you have a different version you'd need to dig through EditorMacro.m to find the correct code for Matlab 6.
if com.mathworks.mlservices.MLEditorServices.getEditorApplication.getActiveEditor.isDirty
thisdocument=com.mathworks.mlservices.MLEditorServices.getEditorApplication.getActiveEditor.getDocument;
thisdocument_text=char(thisdocument.getText(0,thisdocument.getLength));
fid = fopen('backupfile.m','w');
fprintf(fid, '%s', thisdocument_text);
fclose(fid);
else
% saved file is unmodified in editor - no need to play tricks...
...
end
So the if-condition checks if the currently active editor window contains a file which is not saved ("dirty"); if it is, we need to retrieve the current version of the code (into variable thisdocument_text) and save this string to some file.
Does this help?

My Localizable.strings file has somehow been corrupted and I don't know how to restore it.
If I open it as a Plain Text File it starts with weird characters that I can't copy here.
If I leave the file be the app builds. If I make any changes either the values aren't interpreted properly or I get an error at compile time.
Localizable.strings: Conversion of string failed. The string is empty.
Command /Developer/Library/Xcode/Plug-ins/CoreBuildTasks.xcplugin/Contents/Resources/copystrings failed with exit code 1
I suspect this is an encoding problem but I don't know how it happened (maybe SVN is to blame?) nor how to solve it. Any tips will be much more appreciated.
I have issues with the same file that sound very similar to your own. What happens for me is that Xcode doesn't know the correct file formating. I often get this when rearranging the project and I remove and re-add this file to the Xcode project. When I re-add the file, its encoding gets set to something like Western Roman which can't seem to render anything other than ASCII.
Here's what I do to fix the problem:
In Xcode select the Localizable.stings file in the Groups&Files panel.
Do a Get Info on that file.
On the info panel select the General tab.
In that tab go to the File Encoding and change its value.
The last step is where the trick lies as you now have to guess the right encoding. I find that for most European languages that "Unicode (UTF-8)" works. And for Asian languages I find that "Unicode (UTF-16/32)" are the ones to try.
I just had that error because I forgot a semicolon. Took me a while to figure it out. Seems like a really ambiguous compiler error but the fix was simple.
Make sure in File-Get Info, that UTF-16 is selected. If it's set to none or UTF-8 as encoding then you need to change it. If your characters have spaces between them then you choose to "re-interpret" the file as UTF-16. If there are weird characters in the file, then you need to remove them.
Execpt the UTF-8 problem, sometimes you still have to check the content in case if there are some syntax problems.
Use the following Regular Expression to verify your text line by line, if there's any line not matched, there must be a problem.
"(.+?)"="(.+?)";
You can use the plutil command line tool. Without options or with the -lint option, it checks the syntax of the file given as argument. It will tell you more precisely where the error is.
This happens to me when there is a missing quote or something not right with the file. MOst commonly, since my language files are done by another team member, he tends to forget a quote or something. Usually XCode shows an error on that line, sometimes it does'nt and just throws "Corrupted data" error.
Double check if all your strings are properly closed in quotes
Open the file in Xcode.
Right click it in Project Navigator.
Select Open as -> ASCII Property List
