these are NTFS/SMB illegal character so Samba must mangle them.

That's the Unicode glyph for character in the Unicode private use
range. OS X maps all illegal NTFS characters to the Unicode private
range, the mapping is the venerable SFM sheme.

No, different issue, just as bad. :)

yes. vfs_fruit and

  fruit:encoding = native

cf man vfs_fruit. You'll need 4.2 for that, if you wait a few more
days you'll get 4.2rc3 that'll also ship my AAPL performance patches
for OS X clients.
