mkdir a folder named NVHTarGzip_测试，error message occur.

Error Domain=io.nvh.targzip.zlib.error Code=-2 "Unexpected state from zlib" UserInfo={NSLocalizedDescription=Unexpected state from zlib}

what case this issue is that my folder's name contains chinese words,but encode is used
[destinationPath cStringUsingEncoding:NSASCIIStringEncoding]
if i clear the folder's chinese word ,everything goes well.
