I can't enter it here interactively with the "C-q" trick, because my keyboard setup maps it to a dead key (useful for entering accents), but doing (insert "\^^") in an Emacs buffer and querying the result with "describe character confirms that.

Perhaps because it sounds more bureaucratic ;-) Cheers [1] https://en.wikipedia.org/wiki/C0_and_C1_control_codes#Category-Number_names - t --GUPx2O/K0ibUojHx Content-Type: application/pgp-signature; name="signature.asc" Content-Description: Digital signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.12 (GNU/Linux) iEYEARECAAYFAmD5Qx8ACgkQBcgs9XrR2kav1wCeP6YR8xi5dcJSJIqJESPYnY3b Kd8Anis473adekR0DMD2NE/baehIJ6vO =g2Qk -----END PGP SIGNATURE----- --GUPx2O/K0ibUojHx--
