Uh oh.  1.7.9 is old.  Please update.

Dunno.  This is not what I see.  What did you have $LANG and $LC_CTYPE
set to?  Here's what I see:

  $ uname -a
  CYGWIN_NT-6.1 vmbert7 1.7.16(0.261/5/3) 2012-07-09 14:51 i686 Cygwin

  $ echo $LANG
  C.UTF-8

  $ echo "Rücken" > ttt.txt
  $ od -c ttt.txt
  0000000   R 303 274   c   k   e   n  \n
  0000010

  $ gawk '{print "Length: " length($0)}' ttt.txt
  Length: 6

  $ gawk --version | head -1
  GNU Awk 4.0.1
