Texts-Together-OneCSVperFile are not in UTF-8

[gsarti]

I am experiencing some difficulties when loading the files using python's Pandas library since they do not appear to be in the standard utf-8 format.

I tried to use the charade to determine the original encoding and the suggested one is ISO-8859-2, but even converting from ISO-8859-2 to UTF-8 produces wrong characters.

Is it possible to address this? It would just require to convert the set of CSV to UTF-8 and replace the ones currently on Zenodo.

Just another user passing by. UTF-8 and ascii don't work for sure. cp-1252 is your best bet. Delete WNL Scarlett file before you run code.

But be minded that cp-1252 also produces wrong characters.

ran into the same issue today. hasn't been solved as far as i can see. really nasty to see some noise introduced into the dataset due to misaligned encodings :(

On TextsSeparatedByReading Level, try this script. This will give the output files that you need. @mnbucher

hi @brucewlee thanks for the code. i managed to write my own version and hope i minimized the noise of the encoding in it. currently confused by the dataset size though. the paper states that "The corpus consists of 189 texts, each in three versions (567 in total". but i actually have 7278 samples after parsing all TXTs. has the dataset been massively extended after the original publication?

[brucewlee]

@mnbucher No. In my experience, the corpus size is the same as stated in the paper. In the above script, see txt2csv instead of pairwise_txt2csv. The latter creates pairwise instances.
