Title:
  man pages are not displayed correctly

Status in gnome-terminal package in Ubuntu:
  New
Status in man-db package in Ubuntu:
  Incomplete

Bug description:
  Many man pages are not displayed correctly. For example, "man bash" or
  "man 3 printf" do not display correctly.

  If I do "man 3 printf" and copy/paste the output (below), the output
  looks normal, but it does not look normal in my terminal screen! It is
  totally messed up!

  This just started after I upgraded from Ubuntu 15.04 to 15.10. I have
  been using Ubuntu for years, and I have never had any problem with the
  display of the man pages until now.

  I took a screenshot of my terminal page to show how it looks and
  attached it along with the man debug output.

  Copy/paste output snippet:

  PRINTF(3)
  Linux Programmer's Manual
  PRINTF(3)

  NAME
         printf, fprintf, sprintf, snprintf, vprintf, vfprintf, vsprintf, vsnprintf - formatted output conversion

  SYNOPSIS
         #include <stdio.h>

         int printf(const char *format, ...);
         int fprintf(FILE *stream, const char *format, ...);
         int sprintf(char *str, const char *format, ...);
         int snprintf(char *str, size_t size, const char *format, ...);

         #include <stdarg.h>

         int vprintf(const char *format, va_list ap);
         int vfprintf(FILE *stream, const char *format, va_list ap);
         int vsprintf(char *str, const char *format, va_list ap);
         int vsnprintf(char *str, size_t size, const char *format, va_list ap);

     Feature Test Macro Requirements for glibc (see
  feature_test_macros(7)):

         snprintf(), vsnprintf():
             _BSD_SOURCE || _XOPEN_SOURCE >= 500 || _ISOC99_SOURCE || _POSIX_C_SOURCE >= 200112L;
             or cc -std=c99

  DESCRIPTION
         The  functions  in  the printf() family produce output according to a format as described below.  The functions printf() and vprintf() write output to stdout, the standard output stream; fprintf() and vfprintf() write
         output to the given output stream; sprintf(), snprintf(), vsprintf() and vsnprintf() write to the character string str.

         The functions snprintf() and vsnprintf() write at most size
  bytes (including the terminating null byte ('\0')) to str.

         The functions vprintf(), vfprintf(), vsprintf(), vsnprintf() are equivalent to the functions printf(), fprintf(), sprintf(), snprintf(), respectively, except that they are called with a va_list instead of  a  variable
         number of arguments.  These functions do not call the va_end macro.  Because they invoke the va_arg macro, the value of ap is undefined after the call.  See stdarg(3).

         These  eight  functions  write the output under the control of a format string that specifies how subsequent arguments (or arguments accessed via the variable-length argument facilities of stdarg(3)) are converted for
         output.
