I am in luck :-) simple 'export LC_CTYPE=utf-8 is work, In fact, utf-8
and MacRoman are very similar:

      Font Encoding

The default font encoding in Mac OS X is MacRoman. The default font
encoding on some other platforms is ISO-Latin-1 or WinLatin-1. These are
subsets of UTF-8 which means that files or filenames can be turned into
UTF-8 by just turning a byte into a char. Programs that assume this
behavior cause problems in Mac OS X.

The simplest way to work around this problem is to specify a font
encoding explicitly rather than assuming one.

If you do not specify a font encoding explicitly, recognize that:


      In the conversion from Unicode to MacRoman you may lose information.


      Filenames are not stored on disk in the default font encoding, but
      in UTF-8. Usually this isnt a problem, since most files are
      handled in Java as |java.io.File|s, though it is good to be aware of.


      Although filenames are stored on disk as UTF-8, they are stored
      decomposed. This means certain characters, like e-acute () are
      store as two characters, e, followed by (acute accent). The
      default HFS+ filesystem of Mac OS X enforces this behavior. SMB
      enforces composed Unicode characters. UFS and NFS do not specify
      whether filenames are stored composed or decomposed, so they can
      do either.
