Description of problem: Using UTF-8 encoding with wide characters are not interpreted correctly.

How reproducible: always/deterministic


Steps to Reproduce:

  * add folowing line to /etc/rhn/rhn.conf
        java.login_banner = >>>\u00e1\u00fd<<< >>>áý<<<
  * observe login page

Actual results:
  * wide characters are "broken". Escaped-ones are ok,
    but native utf-8 characters are trash

Expected results:
  * ">>>áý<<< >>>áý<<<" on login page

Additional info:
  as can be seen, workaround exist, escaping can be done
  by `native2ascii` tool
