Hah!  Great minds think alike.

But they missed a few files (not Makefiles).  The following shell command finds 
every openwrt file that's not UTF-8 (and isn't obviously binary).  It works 
because '.' matches only properly-encoded characters.  You may need a new GNU 
grep for this command to be reliable.

LC_ALL=en_US.utf8 grep -lv '^.*$' \
  $(git ls-files | grep -Ev '\.(patch|bin|squashfs)$')
