 UFS is a traditional Unix filesystem, and will not mangle your filenames.

 ZFS apparently acts like a case-sensitive HFS+: it still tries to
 normalize to UTF-8 (and does it badly, at that - picking an Apple-specific
 almost-NFD form of normalization rather than the more sensible NFC form).

 So ZFS may not corrupt cases, but it still corrupts UTF-8 filenames.

Not sure if that is always the case.  This thread suggests otherwise:
http://opensolaris.org/jive/thread.jspa?threadID=53303&tstart=0

Case sensitivity and mangling look like they are configurable.  See
the "casesensitivity" and "normalization" options at
http://docs.sun.com/app/docs/doc/819-2240/zfs-1m

ZFS on OSX may just default to "insensitive" and some form of
normalization especially if they were/are thinking about making it the
default fs and wanted backwards compatibility for broken apps.
Randal, can you make a new FS with casesensitivity=sensitive and
normalization=none and see how it behaves?
