    tmac/tty.tmac: Give non-Unicode glyphs fallback.
    
    * tmac/tty.tmac: Define fallback glyphs for Bell Systems logo
      (non-breaking adjustable space) and radical extension and square root
      extension (both non-printing input breaks) to suppress warnings from
      groff_char(7).  As none of these are encoded in Unicode it seems
      unlikely they will become supported soon.
