DBERROR "strange character": db4

[Arnau Bria]

Hi,

I've updated my gentoo, and when I restarted the service, I find that
it does not work, and I find a very strange character in the error: a
interrogation mark in a black circle...

I looked for it in google, but I found nothing, could someone help
 to find what is the service telling me?

I'm using cyrus-imapd-2.2.12-r4

TIA,
