MATLAB: How to get the MATLAB editor to display and read characters in another encoding

editorencodingMATLAB

I need to read some m file written with comments in Japanses. However since my system locale is in Chinese, the comments displayed in the MATLAB editor is a total mess. When I change my system locale to Japanese, those comments can be displayed in the MATLAB editor correctly. I think those m file is in some Japanses enoding like Shift_JIS or EUC_JP, not in UNICODE. Can I solve this problem without changing my system locale?

As dpb menstioned, the answer is ... no.

As you expected, 'ja_JP.Shift_JIS' is used for Japanese encoding in Windows OS with Japanese locale.

you can confirm your MATLAB system encoding using following command:

feature locale

As a workaround, please try to use an external text editor which can change text encoding.

MATLAB: How to get the MATLAB editor to read UTF-8 characters? UTF-8 characters in blank squares in editors, but in the command window and workspace works fine.

I have a very tricky way to solve this problem. And it seems works. In my case, (windows matlab 2016b x64)

feature('locale')

always output below even I have modified lcdata.xml

ctype: 'zh_CN.GBK'
...

so, I delete this in lcdata.xml (in codeset)

<encoding name="GBK">
    <encoding_alias name="936">
</encoding>

then I change following

<encoding name="UTF-8">
    <encoding_alias name="utf8"/>
</encoding>

<encoding name="UTF-8">
    <encoding_alias name="utf8"/>
    <encoding_alias name="GBK"/>
</encoding>

The point is cheat matlab GBK is just alias of utf8

MATLAB: Unicode characters in .m file

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.
