How to change locale settings
Background
In computing, a locale is a set of parameters that defines the user's language, region and any special variant preferences, that the user wants to see in their user interface. Usually a locale identifier consists of at least a language code and a country/region code.
For example, a locale setting for your computing environment will affect the presence of special characters, sorting order, as well as some other values, such as the currency symbol.
The Issue
It is convenient to have the locale of your computer set to your preferred value. However, when you use your SSH client to connect to a remote computer, such as the ARC cluster, the SSH client will translate your locale settings to your remote session on the remote computer. It will set the current locale to the value you have on your personal computer. The problem will arise if such a locale is not available on the remote computer.
