samba - May 2003 - Mac OS X canonically decomposed UTF-16 filenames

Hi.

I'd like to find some way for Samba to convert the filenames created
by Macintosh OS X into something windows can use.

According to their docs:

   
http://developer.apple.com/techpubs/macosx/Essentials/SystemOverview/FileSystem/chapter_9_section_13.html

filenames are stored as

   canonically decomposed Unicode 2.1 in UTF-16 format (a sequence of
   16-bit codes)

Samba running on a mac seems to work okay.  It's when I write data to
an NFS volume where I get in trouble.  I'm running samba on a linux
that exports NFS shares for Mac systems.

So.. my question is:

  * Did Apple patch Samba?  Or is the libc doing something to convert
    the characters?

  * I'm trying to get Samba 3.0 to work.  Does anyone know which, if
    any iconv encoding can deal with the on-disk format of mac
    filenames?

An example filename is available at:

  http://www.inuus.com/macfilename.html

  Rino??c??ero??se

this should appear as:

  Rin??er?se

(assuming the iso-8859-1 encoding of this email message works...)

Any and all help on this is appreciated...

Take a look at the Baltra project for MacOS-X info:

http://www.baltra.org

There is some general information there for using Unix, Win, MacOS9, and
MacOS-X all on the same network while keep things reasonably sane
(filenames, Mac resource forks, etc.). 

From my experience, MacOS-X seems to work well when connecting to a Samba
3.0 server.  When UTF8 names are enabled in smb.conf, you should be able
to share the same filing system via NFS or AFP with a Baltra-patched
Netatalk.  Funky chars (like the trademark char) seem to work across all
platforms and protocols.

If I remember right, most of Apple patching to Samba was for Kerberos
authentication.  If curious, you can get their Samba and diff it against
the corresponding Samba release to see what they did.
