Sounds like you want to change your
locale in the console and observer what comes up (Note if LC_ALL= is set to something, this over rides all other settings).
If you want to change the numbers to english decimal (en_US.UTF-8), enter the following:
su - (switch to root)
Try it out now and see.
Environment variables implement the locale codes. For example LANG=en_US.UTF-8 specifies that the computer uses US English with a UTF-8 encoding when displaying information.
Note: Type in
locale -a to ensure you have the en_US.UTF-8 installed. If now use POSIX if you have that (I believe this is nessary but I am starting to doubt it now, most distro's will have that even if it isn't shown?)
