I've seen this with other web based apps. It usualy happens when tere is a control character in the text unfortunitly most text editors will simply ignore the character so it makes it hard to diagnose. If this is only happening with email related messages (which is not un-common) you may need to handle it at your mail server. Specificlty in the perl script that apears to be generating the message. Here is a regex I've used in the past in webforms where people would often copy and past fields from outlook that helped with the same error s/\P{IsPrint}//g this regex will strip out any characters that are not unicode printable. -----Original Message----- From: ml@bortal.de Subj: [syslog-ng] Encoding provlem when writing to postg res Date: Wed Oct 15, 2008 3:53 am Size: 1K To: syslog-ng@lists.balabit.hu Hello List, i get the following error when i try to write to postres: Error running SQL query; type='pgsql', host='XXX', port='', user='XXX', database='syslogng', error='ERROR: invalid byte sequence for encoding "UTF8": 0xe96461\x0aHINT: This error can also happen if the byte sequence does not match the encoding expected by the server, which is controlled by "client_encoding".\x0a', query='INSERT INTO msg_table (msg_rcv_time, msg_sent_time, hostname, msg_facility, msg_priority, msg_text) VALUES (\'2008-10-14T19:59:46+02:00\', \'2008-10-14T19:59:46+02:00\', \'foo\', \'mail\', \'warning\', \'mimedefang.pl[3497]: Message contains more than one Subject: header: Bulletin d\\\'\'info d\\\'\'Enseigner.TV et la fiche p\xffdagogique de l\\\'\'\xffmission du mois \xff 14 octobre 208 --> Bulletin d\\\'\'info d\\\'\'Enseigner.TV et la fiche p\xffdagogique de l\\\'\'\xffmission du mois \xff 14 octobre 208\')' How can i fix this?
