MATLAB: How to save unicode characters in m-files and display them in figures using m-files

MATLABunicode charactersunicode support

Unicode characters (Hebrew letters, in my case) are not saved in m-files. After saving and re-opening the file I see blocks instead of the unicode characters. Also, when I try to display unicode characters in a figure, I get blocks; however, command line works fine and also displaying unicode characters that were read from a file. I tried to apply the solution given here, but this did not solve the problem and displayed garbage. Any solution?

I managed to resolve this issue by renaming the file MATLABroot\bin\lcdata_utf8.xml to lcdata.xml.

For R2017a, the steps are similar to the ones described in https://www.mathworks.com/matlabcentral/answers/280988-how-do-i-get-my-matlab-editor-to-read-utf-8-characters-utf-8-characters-in-blank-squares-in-editors. The only difference is that the matlabroot/bin/lcdata.xml file no longer describes all standard locales and encodings. But you can still use this file for customizing the locale database.

For my case, the encoding is windows-1252 (you can find your encoding using the feature('locale') command), and therefore, I added the following lines to the <lcdata> ... </lcdata> block in lcdata.xml.

<codeset>
  <encoding name="UTF-8">
    <encoding_alias name="windows-1252" />
  </encoding>
</codeset>

Just modify based on your own system encoding.

Simply call them one right after the other

EDIT Updated in response to an email from Sherif...

I looked at the files, found here for anyone else who is interested. These are scripts, and horribly named at that. The first thing you have to do is rename them so that the number is at the end of the name, not the beginning, as MATLAB doesn't recognize names like 1myfile. Change it to myfile1.

Then, looking at the code, we find horrific coding practices, not the least of which is growing huge arrays in FOR loops. Thus the files are very slow. Finally, the second file (or what we can only guess is the second file by the 2) calls a function AWGN, which I don't have. It turns out that this file is part of the communications toolbox, which is not listed as a requirement (go figure). If I had this file, I think the code would run.

So, if you have the communications toolbox, rename the files as I did, then call them one after the other. Though judging by the terrible coding practices, I would not guarantee any outcome whatsoever.
