Reading zipped utf-16 file: AttributeError: 'UTF8Recoder' object has no attribute 'seek'

Code Sample, a copy-pastable example if possible

df = pd.read_table('myfile.zip', 
                   compression='zip',
                   encoding='utf-16')

Hmmm...that looks kind of odd. Mind sharing the ZIP file for us to reproduce?

[nickeubank]

@gfyoung sorry for delay -- couldn't upload original file, but here's what seems to be a minimal working example

sample.zip

[gfyoung]

Yep, can reproduce this error. Investigation and PR patch is welcome!
