In general, when working with open source always respond to the  
mailing list. The mailing lists are archived and are searchable via  
google, etc. so others get the benefits to the answers to your  
questions.

First, you would want to get a copy of the original log file and send  
it along without touching it so anyone viewing it can be sure they are  
seeing the original data. Zip it up and then transfer it in binary so  
you are sure that the data isn't being touched.

Next, you might actually have to look at the code that is generating  
the log record in question. It may be that variables are being  
replaced and for some reason those variables are the source of the  
problem.

Also, find out what code page the host system is set to and then see  
if you can configure your system that way. That can get tricky as your  
keyboard won't have the correct characters, but you should be fine for  
Italian since so many of the Latin 1 characters are common.

That isn't a problem. I started out as a computer operator on IBM  
mainframes and was a CICS systems programmer for a few years (back in  
the dark ages when IBM gave you the source code). I worked at Candle  
Corp for 17 years working on performance monitoring products for IBM  
systems (MVS - z/OS, VM, AS/400) and the last several years we were  
doing all our work on Unix System Services so we could have a common  
build system across all the various operating systems we supported. I  
haven't worked on a mainframe since 2001 though and switched from C/C+ 
+ to Java at the same time, but I'm not sure much has changed.
