SyslogHandler doesn't handle multi-byte characters correctly.
I tried to log multi-byte message with both of org.jboss.logmanager.handlers.SyslogHandler and org.apache.log4j.net.SyslogAppender for same message, only SyslogHandler output were corrupted.
Step to reproduce (It might need to define -Dfile.encoding=UTF-8 in _JAVA_OPTIONS):
1. define a facility local1 at localhost and make syslog accept UDP packets.
2. define a logger:
/subsystem=logging/logger=utf8mb4log:add(level=INFO)
3. define a SyslogHandler:
/subsystem=logging/custom-handler=TEST_SH:add(class="org.jboss.logmanager.handlers.SyslogHandler", module="org.jboss.logmanager", formatter="SyslogHandler: %s%e", level=INFO, properties={serverHostname="localhost:514", facility="LOCAL_USE_1", truncate=false, maxLength=1024, syslogType="RFC3164" })
/subsystem=logging/logger=utf8mb4log:assign-handler(name=TEST_SH)
4. define a SyslogAppender:
/subsystem=logging/custom-handler=TEST_LOG4J:add(class="org.apache.log4j.net.SyslogAppender", module="org.apache.log4j", formatter="log4j: %s%e", level=INFO, properties={syslogHost="localhost:514", facility="local1"})
/subsystem=logging/logger=utf8mb4log:assign-handler(name=TEST_LOG4J)
5. get and deploy example project at https://github.com/lbtc-xxx/utf8mb4log
6. Access the servlet http://localhost:8080/utf8mb4log/
And you will get like this: (I can't put 4 byte UTF-8 characters here... because database error occured):

I would send a pull request later.
