If the user has an invalid environment setting then it is possible for the call to set locale to fail, so there are only two possible actions, the first is to throw a runtime exception and cause the program to quit (default behaviour), or the second is to modify the environment to something sensible (least surprising behaviour). The follow code produces the least surprising behaviour. It will use the user specified default locale if it is valid, and if not then it will modify the environment the process is running in to use a sensible default.
