Hi Mattia, I asked about the locale matter before and you were able to confirm that it's wxWidgets that is outputting this message - seen here in out of the tests for Padre:
t/15-locale.t .............. 1/7 09:15:23: Error: Cannot set locale to 'de_DE' The issue is that on my system, I don't have the German locale installed, so I get the Error when the test has Padre change locales to de. Given that people rarely change their languages during runtime of an application, this isn't something I would say gets seen that often, however it does raise questions - for the wrong reasons - when it does happen. Is there any chance this Error could be suppressed? Or is this something that shouldn't be done and it's fine to just ignore the warning? I'm not sure it actually provides anything useful for either the user or the programmer, but happy to accept that status quo and will do more to document the feature for next time we all start wondering what that means. Thanks, Peter.
