That makes sense.

I believe it's part of smb.conf.  See the display|dos|unix charset
options.

BackupPC doesn't use a shell to execute commands like
$Conf{SmbClientIncrCmd}.  You need to put commands like
this in a shell script and point $Conf{SmbClientIncrCmd}
at your shell script.

> How to modify backuppc to use the good charset for files with smb ?

As I mentioned in my earlier email, some development is required
to make BackupPC handle different charsets correctly.  As you
are finding out, it also depends upon how each XferMethod
handles charsets too.
