Encoding issue in reported.tsv

[somerandomguyontheweb]

As discussed here, comments in reported.tsv for Belarusian, which were filled in by the contributors, are not displayed correctly: all Cyrillic characters have been replaced with question marks (probably an encoding issue at some stage of the data pipeline).

Steps to reproduce:

• Download the Belarusian dataset, unpack it and open cv-corpus-7.0-2021-07-21/be/reported.tsv.
• Filter by reason, hiding all sentences with the reason grammar-or-spelling.
• Observe that most of the remaining reasons are not displayed correctly.
