This is because of the locale settings. I changed the script to show the locale (and to be plain text so the spaces are visible).

You can probably change this in your script (for example, php provides a way <http://php.net/manual/en/function.setlocale.php>, perl likely has one too) and there is a third-party module that claims to set the locale for the whole server. Your OS might also give you a way to set it for the whole server. - Y On Fri, Jul 1, 2016 at 4:34 PM, Rob McAninch <rob.mcani...@gmail.com> wrote: > Server version: Apache/2.4.10 (Debian) > > This seems like it should be simple but manual pages and searching have > not shown me an answer yet.
