> According to references [1], [2]:
> In .csv, the double quote is a special character as it can optionally enclose a text field. But in .tsv, it is not a special character, and it can appear anywhere and when it does, it should treated as a literal. The tsv format specification also does not provide for the tab or CR/LF characters to show up anywhere in text fields. However, Drill treats tsv very the same like csv.
> For an example, given data:
> {code}
> "test"\t"test"
> {code}
> A query: select columns[0], columns[1] from `t.tsv`; Drill would give
> {code}
> test      test
> {code}
> However, according to the reference[2], it is supposed to be
> {code}
> "test"      "test"
> {code}
> Ideally, the Drill should follow the standard see[2].
