I’ve been having some problems with charsets (character sets) when using FreeNAS, rsync, deltacopy, and cygwin.
The filenames on a Windows box are either in UTF-8 or ISO-8859-1 (Latin1). The FreeNAS uses rsync to backup the files on the windows box, and saves them to a RAID array. I wasn’t sure if it was rsync, or FreeNAS causing the problem, but all characters with more than 7 significant bits (8 or more) were being “escaped” such as \#303 instead of Ñ.
I found the solution by using the “-8″ flag in rsync. Also, I overwrote the cygwin.dll file supplied by DeltaCopy with a UTF-8-modified cygwin.dll, restarted DeltaCopy, and the filenames appeared correctly and in UTF-8 (instead of ISO8859-1).
As always, remember to BACKUP before journeying on with this! Good Luck!
