Set Locale on macOS Platforms

On the Apple macOS platform, MATLAB® reads the user locale setting. MATLAB automatically chooses a codeset for each combination of language and territory.

If you customize the locale setting, MATLAB ignores the customized portion. MATLAB ignores the LANG environment variable and the Terminal application locale setting.

MATLAB does not support every locale setting. If your locale is not supported, MATLAB uses the default locale en_US_POSIX.US-ASCII, also known as C locale.
