rsync plus cygwin: language problems with filenames

[Steve Robinson]

I know this problem has been posted before, but I have been unable to 
find a solution on this list or anywhere else on the net.  Let me review.

First, here is my setup:
OS: Windows XP Pro SP2
Rsync: 2.6.6-1
Cygwin: 2.510.2.2

Whenever I transfer any file that has Japanese characters in it, the 
following message appears in the screen output:

C:\Documents and Settings\Steve>rsync -avvz --delete /cygdrive/c/test 
/cygdrive/c/test2
building file list ...
file has vanished: "/cygdrive/c/test/01 - ??????????.mp3"
done
deleting in test
IO error encountered -- skipping file deletion
delta-transmission disabled for local transfer or --whole-file
test/New Text Document.txt is uptodate
total: matches=0  tag_hits=0  false_alarms=0 data=0

sent 119 bytes  received 32 bytes  302.00 bytes/sec
total size is 0  speedup is 0.00
rsync warning: some files vanished before they could be transferred 
(code 24) at
 /home/lapo/packaging/tmp/rsync-2.6.6/main.c(791)

So far, this is the best explanation I have found for what may be happening:

Also, people have pinned it down to a Windows language setting problem:
http://lists.samba.org/archive/rsync/2005-May/012611.html

I confirmed this for myself by going into Regional and Language Options, 
Advanced, and choosing Japanese for the language I wanted to use in 
non-Unicode programs.  Now, it will transfer the Japanese files fine.  
It will also transfer most English language files.  However, it then has 
a problem with accented letters, which I assume must have been part of 
the English (United States) settings.

I further proved that it is very likely just a Windows problem by trying 
to copy one of the files in Ubuntu Linux.  It worked perfectly with 
rsync 2.6.5 and I bet it would've done the same thing with 2.6.6.

Has anyone made any progress in solving this problem?  I noticed that 
the NEWS file for rsync 2.6.7 
(http://www.samba.org/ftp/rsync/rsync-2.6.7-NEWS) discusses an 
improvement in escaping unreadable characters.  Is that related to this 
problem?  I'm new to cygwin and I'm not sure which binary I should be 
using or whether I have to wait for cygwin to come out with it in their 
own system.

I'd really like to get this to work.  This is one tiny problem in an 
otherwise flawless solution to my backup needs.  Please let me know if 
you have any ideas to make this work.

Thanks for reading.
