Thank you for the reply.
It worked for the 'product_name', and read all the lines. Something wrong, however, against the other columns like 'job', 'gender', etc
job
1 "\u0090³\u008eÐ\u0088õ\u0081E\u008cö\u0096±\u0088õ"
2 "\u0090³\u008eÐ\u0088õ\u0081E\u008cö\u0096±\u0088õ"
gender
1 "\u0092j\u0090«"
2 "\u0092j\u0090«"
age
1 "50\u0091ã"
2 "50\u0091ã"
Along with the error:
Warning: 1 parsing failure.
row col expected actual file
17511453 -- 20 columns 11 columns '01studysample_SCIData.tsv'
It really confused me, how can the file be like this with different encoding.
