Not working on mac standalone build

I get this error when I try unzipping a zipped file

NotSupportedException: Encoding 437 data could not be found. Make sure you have correct international codeset assembly installed and enabled.

The description mentions it works on mac, doesn't it!? Could any explain the issue? Thanks in advance
