Hi, After many problems, I have finally been able to setup OTRS with UTF-8 as the DefaultCharset. I originally installed OTRS without unicode support and with perl5.6 and that cause problems when I moved to unicode because the database was in SQL_ASCII. This is all fixed now (perl 5.8, unicode in the database, DefaultCharset=utf-8), but now I'm seeing problems in the mails sent by OTRS. The notifications are sent in the ISO-8859-15 encoding, which is causing obvious problems because the content of the email is actually unicode. Also, the responses sent to customers is sent with unicode headers, but doesn't show up properly in Thunderbird, even though thunderbird thinks the mail is indeed unicode. The first attached message is a typical autoresponse and has a iso-8859-15 encoding. The second attached message is a response done by an agent and has the following encoding: Content-Type: text/plain; charset="utf-8" Content-Disposition: inline Content-Transfer-Encoding: 8bit Any help would be appreciated because right now all responses from my agents go out corrupted.
