error opening files with Matlab Editor

Matlab starts up, and when requested Matlab's editor starts up without problems. However, when trying to open self-made Matlab scripts and functions, the following error message appears:

Caught "std::exception" Exception message is: locale::facet::_S_create_c_locale name not valid

and the script won't load into the editor.

If I (use another editor to) purposefully edit some erroneous code into the script and let Matlab run it to generate an error message with a link, clicking it will open the script correctly into Matlab's editor.

• Ubuntu Linux 12.04.2 LTS, accessed by remote login
• Matlab version R2014a
• Matlab was installed with sudo in /usr/local, with symbolic links to Matlab's own scripts and function by linking to /usr/local/bin

N.B. This seems to be a problem with the locale , but I don't know what needs to be changed.

I'm observing same behavior with matlab R2013b and R2014a un a (k)ubuntu 14.04 linux 64 bit. not with matlab R2013a.

Error message: Caught "std::exception" Exception message is: locale::facet::_S_create_c_locale name not valid

appears when opening, writing or reading files.

any suggestions welcome!

fixed it by settin /etc/defaults/locale to: LANG=en_GB.UTF-8 LC_CTYPE="en_GB.UTF-8" LC_MESSAGES=en_GB.UTF-8 LC_ALL="en_GB.UTF-8" LC_NUMERIC="en_GB.UTF-8" LC_TIME="en_GB.UTF-8" LC_MONETARY="en_GB.UTF-8" LC_PAPER="en_GB.UTF-8" LC_NAME="en_GB.UTF-8" LC_ADDRESS="en_GB.UTF-8" LC_TELEPHONE="en_GB.UTF-8" LC_MEASUREMENT="en_GB.UTF-8" LC_IDENTIFICATION="en_GB.UTF-8"

and in the bash: . /etc/default/locale

I am having the same issue with matlab R2015A and Ubuntu 14.04.2.

I have followed the suggestions found on the Internet by rebuilding locales and modifying the files of /etc/default/locale /etc/environment and $HOME/.pam_environment to be similar to what Dominik proposed.

Any input will be appreciated.

In the end, the workaround in this answer did the trick.

After matlab starts run the following command

setenv('LC_ALL','C')

Then you will be able to open .m files.
