  dnl configure sets LC_ALL=C early on, so this range should work.
  case "$var" in
    *[[^\ -~]]*) AC_MSG_ERROR([Emacs cannot be built or installed in a directory whose name contains non-ASCII characters: $var]) ;;
  esac

This is quite drastic.  Do we understand what is the underlying
technical reason for the build failures?  The bug reports didn't give
any explanations, only the fact that moving to a pure-ASCII directory
fixed the problem.
