Q:

Terminal improper output, unprintable character

Ever since I have used vnstat and vnstati, not a single time have I received a proper date under the day column for vnstat. Also, vnstati screenshots display unprintable characters.
Please help me solve this problem.
Screenshots:
1:vnstat

2:vnstati

Thank you

After a brief conversation in the comments...

we checked the output of the date command
we checked the date format configuration in the /etc/vnstat.conf file
we checked the Terminal app preferences in the encoding tab
we checked the language settings in System Settings/Language Support

It was found that by setting the Language Support regional format (from India) to English (US) and applying it system wide, fixed the problem with vnstat displaying odd characters in the date field.
A log out may be necessary for the changes to take effect. :)
