UTF-8 encoded /etc/issue may not be properly displayed by ssh in RHEL 6

Solution Verified - Updated -

Issue

  • We use UTF-8 encoded /etc/issue files, configured in sshd to be displayed on connection. With RHEL 4 and 5 the accents are properly displayed. In RHEL 6, they are not, the escaped octal values are displayed instead. All locales are set to UTF-8 encoding using the proper environment variables. For example:

    • Connection from RHEL 6 (incorrect):

      $ ssh server
      AVERTISSEMENT: L'acc\303\250s \303\240 ce syst\303\250me est restreint.
      
    • Connection from RHEL 4 (correct):

      $ ssh server
      AVERTISSEMENT: L'accès à ce système est restreint.
      

Environment

  • Red Hat Enterprise Linux (RHEL) 6
  • OpenSSH 5.1
