Is this because more people started using UTF-8 recently? -Dimitry --Apple-Mail=_D0BD42B3-4C9C-49CC-8EA4-BC24F0E0EEA7 Content-Transfer-Encoding: 7bit Content-Disposition: attachment; filename=signature.asc Content-Type: application/pgp-signature; name=signature.asc Content-Description: Message signed with OpenPGP using GPGMail -----BEGIN PGP SIGNATURE----- Version: GnuPG/MacGPG2 v2.0.30 iEYEARECAAYFAldYmUUACgkQsF6jCi4glqO8LgCffANHlFKTtOZX7oZ1EGWY5ZKr QeIAoKe6SX/dcZYepuqi/h6dfXkD3utO =61O0 -----END PGP SIGNATURE----- --Apple-Mail=_D0BD42B3-4C9C-49CC-8EA4-BC24F0E0EEA7--
