window containing these characters, you can type the characters, but if you display the

contents of the variable, the characters are corrupted.

Or if you share MATLAB text files with a user on a computer with different locale

settings, they might see corrupted text. The characters are rendered in that user’s locale,

not the language it was written in.

MATLAB text files include scripts and user-defined functions and classes. MATLAB

displays characters in a text file using an encoding scheme, which is defined in the

MathWorks locale database. This encoding scheme supports characters for the language

specified by the user locale setting. If you try to use non-7-bit ASCII characters in a text

file, you might have to use a different encoding scheme. UTF-8 is often used to handle

multilingual characters. Beginning in R2011b, to handle non-7-bit ASCII characters, you

can change the default encoding scheme to UTF-8 by switching the MathWorks locale

database. Note that changing the default encoding scheme might cause characters other

than 7-bit ASCII characters in existing text files to be garbled.

See How the MATLAB Process Uses Locale Settings for more information.

How to Change MATLAB's Default Encoding to UTF-8

If you have text files containing non-7-bit ASCII characters, you must convert the

encoding in the files before changing the default encoding on your computer. For

instructions, see “How to Convert Text File Encoding to UTF-8” on page 7-6.

You can change the default encoding scheme on Mac OS X platforms by using the UTF-8

locale database found in the matlabroot/bin folder.

To change the default locale database, type:

mldir = fullfile(matlabroot,'bin');

copyfile(fullfile(mldir,'lcdata.xml'),...

fullfile(mldir,'lcdata_default.xml'));

copyfile(fullfile(mldir,'lcdata_utf8.xml'),...

fullfile(mldir,'lcdata.xml'));

Alternatively, you can change the default locale database by setting an environment

variable on your computer.

Set the environment variable, MWLOCALE_LCDATA_FILENAME, with the UTF-8

version of the locale database name, lcdata_utf8.xml, in the environment file,

environment.plist. Please see this article from the Mac OS X Developer Library,
