Perhaps.  I found this code in child_setup_tty (in
sysdep.c).

#if 0  /* This causes bugs in (for instance) telnet to certain sites.  */
  s.main.c_iflag &= ~ICRNL;     /* Disable map of CR to NL on input */
#ifdef INLCR  /* Just being cautious, since I can't check how
                 widespread INLCR is--rms.  */
  s.main.c_iflag &= ~INLCR;     /* Disable map of NL to CR on input */
#endif
#endif

I tried to change the first line above to "#if 1".  The
newly build emacs doesn't do CR->LF conversion, thus works
well with the test case (utf-8-bug.el).
