This did not work - I get this error:

It looks like you can't use `.tell()` during iteration: https://stackoverflow.com/questions/29618936/how-to-solve-oserror-telling-position-disabled-by-next-call","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",1250495688,Misleading progress bar against utf-16-le CSV input,
