This patch allows the user to disable the 8-bit data check in the log
message validator. If you have experienced problems with logging any
unicode (utf-8) messages after v1.6, this option is for you.
The correct way to handle this is to add proper parser support for the
Unicode BOM, defined in RFC5424[1], as NetBSD syslogd does[2], search
for IS_BOM().
