Hi,

I've found a bug in /usr/bin/fmt. It ignores the locale
set by LANG so that isprint() returns false for all the special
characters such as german umlauts. This results in such characters
being ommited in the output of fmt.

This patch (applied to -stable patchlevel 62) fixes the problem:

--- begin ---
*** /usr/src/usr.bin/fmt/fmt.c  Tue May 30 08:30:18 1995
--- ./fmt.c     Mon Apr  1 13:44:35 1996
***************
*** 43,48 ****
--- 43,49 ----
  
  #include <stdio.h>
  #include <ctype.h>
+ #include <locale.h>
  
  /*
   * fmt -- format the concatenation of input files or standard input
***************
*** 84,89 ****
--- 85,91 ----
        register int errs = 0;
        int number;             /* LIZ@UOM 6/18/85 */
  
+       (void)setlocale(LC_ALL,"");
        goal_length = GOAL_LENGTH;
        max_length = MAX_LENGTH;
        setout();
--- end ---

Maybe it should be integrated into -stable. Comments?
